These Terms and Conditions of Sale (“Terms“) govern the sale of products and services by DSTurbo Dawid Sowa, a sole proprietorship (jednoosobowa działalność gospodarcza) registered in Poland, trading as PTT Performance Turbo Technology, with registered office at Cegielniana 4b, 44-200 Rybnik, Poland, tax identification number NIP 6423112413, REGON 360986953, EU VAT number PL6423112413 (“Seller“, “we“, “us“, “our“), and the customer placing an order through the website https://performanceturbo.eu (the “Site“) (“Customer“, “you“, “your“).

By placing an order, you confirm that you have read, understood, and accept these Terms, together with our Privacy Policy, Cookie Policy, Return Policy, Shipping Policy, Warranty Policy, and the Installation & Vehicle Modification Disclaimer, all of which form an integral part of your contract with us.

1. Definitions

• Consumer means a natural person acting for purposes outside their trade, business, craft, or profession, as defined in Article 2(1) of Directive 2011/83/EU, Article 22¹ of the Polish Civil Code, or comparable legislation in the Customer’s country of residence.
• Business Customer means any Customer who is not a Consumer, including companies, sole traders acting within their profession, workshops, tuners, and resellers.
• Product means any turbocharger (new, upgraded/hybrid, or remanufactured) and any related product sold via the Site.
• Built-to-Order Product means any upgraded/hybrid turbocharger, or any other Product, that is manufactured, modified, or configured specifically for the Customer after the order has been placed.
• Order means a Customer’s offer to purchase Products, submitted through the Site checkout.

2. Who can buy

2.1. The Site is intended for persons aged 18 years or older with full legal capacity.

2.2. By placing an Order you represent that: (a) you are at least 18 years old; (b) the information you provide is true, accurate, and complete; (c) your use of the Site and the Products does not violate any law applicable to you; (d) you are not ordering from, nor asking us to ship to, any country subject to comprehensive trade sanctions by the European Union, United Nations, United Kingdom, or United States (a full list of countries we do not ship to is available in our Shipping & Delivery Policy).

2.3. We reserve the right to refuse any Order at our sole discretion, including Orders we reasonably suspect to be fraudulent, placed by resellers we have not authorised, or otherwise in breach of these Terms.

3. Products, descriptions, and availability

3.1. We make reasonable efforts to display product colours, features, specifications, part numbers, OE references, and performance figures accurately. Some variation may occur due to screen calibration, photography, and manufacturer running changes. Published horsepower and torque figures are indicative estimates based on a healthy supporting build and are not a guaranteed result for your specific vehicle.

3.2. All Products are subject to availability. We reserve the right to discontinue any Product at any time without prior notice.

3.3. Compatibility is your responsibility. You are solely responsible for verifying, before purchase, that the Product is compatible with your vehicle’s make, model, year, engine code, transmission, and supporting modifications. OEM part number and engine-code matches are the safest way to verify fitment. If you are unsure, contact us before ordering.

3.4. Images of Products may show representative units. The unit you receive may differ slightly in cosmetic finish, supplier markings, or minor components, provided it is functionally identical.

4. Pricing and currency

4.1. Prices are displayed on the Site in Euro (EUR) . Prices displayed in EUR to Customers shipping within the European Union are inclusive of Polish VAT at the applicable statutory rate. Prices shown to Customers shipping outside the EU are exclusive of VAT, and the Customer is responsible for any import VAT, duties, customs clearance fees, and handling fees in the destination country (see clause 7).

4.2. Shipping costs are calculated at checkout based on weight, destination, and courier service selected.

4.3. We reserve the right to correct any pricing error, typographical mistake, or obvious misprint, even after an Order has been placed. If a correction is material, you will be offered the choice to confirm the corrected price or cancel the Order for a full refund.

4.4. We reserve the right to change prices at any time; the price applicable to your Order is the price displayed at the moment you complete checkout.

5. Orders and contract formation

5.1. An Order placed through the Site is an offer by the Customer to purchase the selected Products on these Terms.

5.2. An automated order confirmation email sent immediately after checkout acknowledges receipt of your offer but does not constitute acceptance.

5.3. A binding contract of sale is formed only when we send you a shipping confirmation email containing tracking information, or — for Built-to-Order Products — an order acceptance email confirming we have commenced manufacture.

5.4. For Built-to-Order Products, we may request additional vehicle information (engine code, VIN, existing modifications, intended power target) before accepting your Order. We are not obligated to proceed until such information has been provided and verified.

6. Payment

6.1. We accept payment through the payment methods displayed at checkout, currently [Visa, Mastercard, American Express, and other cards supported by Stripe]. Payments are processed by Stripe Payments Europe Ltd. (for EU customers) or Stripe Inc. (for other customers). We do not store full card details.

6.2. Payment is taken in full at the time of order submission.

6.3. If your payment fails, is reversed, charged back, or disputed without first contacting us, we reserve the right to suspend or cancel the Order, repossess goods not yet delivered, and/or pursue collection of amounts due plus reasonable costs.

6.4. B2B customers paying by bank transfer or against a proforma invoice must clear full payment before dispatch, unless we have agreed separate credit terms in writing.

7. Taxes, duties, and import fees

7.1. For shipments within the European Union: Polish VAT is applied at the statutory rate for Orders where we are the seller of record. From the moment we reach the EU-wide distance-sales threshold, VAT is applied at the rate of the Customer’s country of residence under the EU One-Stop Shop (OSS) scheme.

7.2. For shipments outside the European Union (including UK, USA, Canada, Switzerland, Norway, Asia, etc.), Products are sold on a Delivered at Place (DAP) basis, meaning:

• The Customer is the importer of record in the destination country.
• The Customer is solely responsible for all import duties, import VAT, customs clearance fees, brokerage fees, excise, or similar charges imposed by the destination country.
• If a shipment is refused at customs, abandoned, or returned to us because the Customer refused to pay import charges, we may deduct the actual return shipping costs and a reasonable handling fee from any refund.

7.3. For UK Customers, Orders below GBP 135 may be subject to UK VAT collected at point of sale once we register for UK VAT; we will display this clearly at checkout when the threshold applies. Orders above GBP 135 are currently shipped DAP.

7.4. For US Customers, we do not currently collect US state sales tax; the Customer is responsible for self-assessing use tax where applicable.

8. Shipping and delivery

Full terms are in our Shipping & Delivery Policy, which is incorporated into these Terms by reference. In summary:

8.1. Dispatch time. In-stock Products ship within 1–3 business days. Built-to-Order Products ship within the lead time quoted on the product page or in your order acceptance email (typically 7–21 business days, plus up to 14 business days if you are sending in a core for upgrade).

8.2. Delivery time. After dispatch, typical courier transit times:

• Poland: 1–2 business days
• European Union: 2–5 business days
• United Kingdom: 3–7 business days
• United States & Canada: 5–10 business days
• Rest of world: 7–14 business days

8.3. Risk of loss passes to the Customer on delivery for Consumers, and on handover to the first carrier for Business Customers (per Article 548 §1 of the Polish Civil Code and Incoterms 2020).

8.4. You must inspect the parcel on delivery. Any visible damage must be noted on the courier’s delivery receipt and reported to us at contact@performanceturbo.eu within 48 hours, with photographs.

8.5. We do not ship to countries listed in Section 3 of the Shipping & Delivery Policy (sanctioned countries and high-risk jurisdictions). Orders placed for delivery to such locations will be cancelled and fully refunded.

9. Right of withdrawal (Consumers in the EU, UK, and EEA)

9.1. If you are a Consumer in the EU, UK, EEA, or Switzerland, you have the right to withdraw from this contract within 14 calendar days from the day you (or a person designated by you, other than the carrier) take physical possession of the Products, without giving any reason.

9.2. To exercise this right, you must notify us unambiguously by email to contact@performanceturbo.eu or by post to Cegielniana 4b, 44-200 Rybnik, Poland before the 14-day period expires. You may use the Model Withdrawal Form set out in our Return, Refund & Withdrawal Policy. The burden of proof of timely withdrawal lies with you.

9.3. In accordance with modern EU consumer standards, we provide a dedicated online withdrawal function. If you wish to withdraw from the contract, you may do so by using the “Withdrawal” button available in your order history on our website. This function allows you to submit your withdrawal statement easily and clearly. Once you submit your request through our online interface, we will immediately provide you with a confirmation of receipt on a durable medium (e-mail). This process does not affect your existing rights to withdraw by email or post, but provides a faster, more convenient way to exercise your right of withdrawal.

9.4. Return shipping costs are borne by the Customer, unless the Product is faulty or incorrectly supplied.

9.5. We will refund all payments received from you for the returned Products, including the original standard-rate shipping cost to you, within 14 days of receiving the returned Products or receiving proof that you have sent them back, whichever is earlier.

9.6. You are liable for any diminished value of the Products resulting from handling beyond what is necessary to establish their nature, characteristics, and functioning (e.g., installing, running, or modifying the turbo).

9.7. Exception – Built-to-Order Products. Pursuant to Article 16(c) of Directive 2011/83/EU and Article 38 point 3 of the Polish Act on Consumer Rights of 30 May 2014, the right of withdrawal does not apply to Products that are: (a) manufactured, assembled, or configured to the Customer’s individual specification; (b) upgraded to a specific Stage, housing size, or compressor/turbine wheel combination selected by the Customer; (c) cores that we have already disassembled, machined, or balanced for the Customer’s Order. All hybrid/upgraded turbochargers at Stage 1 and above are Built-to-Order Products.

9.8. Full details, including the Model Withdrawal Form, are provided in our Return, Refund & Withdrawal Policy.

10. Warranty

Full warranty terms are set out in our Warranty Policy, which is incorporated by reference. In summary:

10.1. New and upgraded/hybrid turbochargers are covered by a 12-month limited warranty from the date of delivery, covering defects in materials and workmanship under normal use.

10.2. The warranty is void if any of the following occur (this list is not exhaustive — see Warranty Policy for the full list):

• improper installation, including failure to prime the oil system, failure to clean the oil supply lines, or incorrect oil feed/drain orientation;
• use of incorrect, contaminated, or degraded oil, or failure to observe the oil-change intervals recommended by the vehicle manufacturer;
• modifications to the turbocharger, its actuator, wastegate, or internal components after delivery;
• operation with a malfunctioning engine (excessive blow-by, cylinder compression faults, boost leak) that causes foreign object damage or overspeed;
• use of software/tuning that exceeds the safe operating parameters for the specific Product;
• competitive motorsport use (track days, drag racing, drifting, rallying, time attack);
• cosmetic wear, paint/finish discoloration from heat, or normal maintenance items (seals, gaskets);
• failure caused by accidents, neglect, misuse, or force majeure events.

10.3. Your statutory rights as a Consumer are not affected by the terms of this limited warranty. In particular:

• EU Consumers: you continue to benefit from the minimum 2-year statutory guarantee of conformity under Directive (EU) 2019/771, and any additional rights under national law (in Poland, the rękojmia under Articles 556 et seq. of the Civil Code).
• UK Consumers: your rights under the Consumer Rights Act 2015 are unaffected.
• US Consumers: nothing in this warranty excludes or limits any implied warranty that cannot be excluded or limited under applicable state law.

11. Installation and vehicle modification – critical disclaimer

This section is summarised; the full text is in our Installation & Vehicle Modification Disclaimer, which you must read before purchase.

11.1. Turbochargers are safety-critical components. You acknowledge that: (a) installation must be performed by a qualified automotive professional with specific experience in turbocharger systems; (b) improper installation can cause engine failure, fire, personal injury, or death; (c) we are not responsible for any damage, loss, or injury arising from installation carried out by anyone, including yourself, a third-party workshop, or us.

11.2. Legal compliance is your responsibility. The fitting of an upgraded or non-OEM turbocharger may:

• void the vehicle manufacturer’s warranty;
• require re-homologation, re-certification, or modification approval in your jurisdiction;
• affect your vehicle’s roadworthiness certificate, MOT/TÜV/Kontrola Techniczna status;
• require notification to your motor insurance provider, failing which cover may be void;
• be unlawful for road use in some jurisdictions.

11.3. For Customers in the United States: the Products we sell are not sold as certified replacements for emissions-control components under the US Clean Air Act (CAA, 42 U.S.C. §7522). Where an upgraded Product would interfere with factory emissions equipment (e.g., DPF, EGR, catalytic converter, O2 sensors), the Product is sold for competition/off-road use only on vehicles not operated on public roads. It is the Customer’s sole responsibility to ensure their use of the Product complies with federal, state, and local law, including the CAA and California Air Resources Board (CARB) regulations. We do not warrant that any Product is legal for on-road use in the United States.

11.4. By placing an Order you represent that you understand these risks and accept full responsibility for lawful use and proper installation.

12. Limitation of liability

12.1. Nothing in these Terms limits or excludes our liability for: (a) death or personal injury caused by our negligence; (b) fraud or fraudulent misrepresentation; (c) any other liability which cannot be limited or excluded by applicable law (including statutory consumer rights).

12.2. Subject to clause 12.1:

For Consumers: our total aggregate liability arising out of or in connection with your Order is limited to the amount you paid for the specific Product giving rise to the claim, plus shipping. We are not liable for any indirect, consequential, or special losses, or for any loss of profit, revenue, business, goodwill, or data.

For Business Customers: to the maximum extent permitted by law, our total aggregate liability for all claims arising out of or in connection with any Order, whether in contract, tort (including negligence), breach of statutory duty, or otherwise, is limited to the amount paid by you for the Product giving rise to the claim. We exclude all liability for any indirect, incidental, special, consequential, exemplary, or punitive damages, and for any loss of profits, revenue, anticipated savings, data, business opportunity, or goodwill, however arising.

12.3. We are not liable for any loss caused by:

• improper installation by a third party;
• failure of the Customer to maintain the vehicle in good running order;
• use of the Product beyond its specified operating parameters;
• events of force majeure (see clause 17).

13. Intellectual property

13.1. All content on the Site – including logos, trademarks, text, photographs, graphics, videos, software, and the arrangement and design of the Site – is owned by us or our licensors and is protected by copyright, trademark, and other intellectual-property laws.

13.2. Trademarks, model designations, and part numbers of third-party vehicle and turbocharger manufacturers (e.g., BMW, Audi, Mercedes-Benz, VAG, Porsche, Garrett, BorgWarner, Mitsubishi, IHI, Hitachi) are used only for identification and reference purposes to describe vehicle compatibility or turbocharger heritage. Our use of such marks does not imply endorsement, affiliation, or sponsorship by those manufacturers.

13.3. You may not copy, modify, reproduce, distribute, or create derivative works from any Site content without our prior written permission, except as permitted by fair use or by mandatory copyright exceptions in your jurisdiction.

14. Force majeure

14.1. We are not liable for any delay or failure to perform that results from events beyond our reasonable control, including: acts of God, natural disasters, pandemic, war, armed conflict, terrorism, civil unrest, governmental action, sanctions, labour disputes, supplier default, courier delay, power or internet failure, or failure of third-party logistics, payment, or software providers.

14.2. If such an event prevents performance for more than 30 days, either party may cancel the affected Order and we will refund any amounts already paid for Products not yet shipped.

15. Governing law

15.1. These Terms, and any contract of sale formed under them, are governed by the law of the Republic of Poland, excluding its conflict-of-laws rules and excluding the United Nations Convention on Contracts for the International Sale of Goods (CISG).

15.2. Consumer protection override. Where you are a Consumer habitually resident in a country of the European Union, the European Economic Area, the United Kingdom, Switzerland, or any other country whose mandatory consumer-protection laws would apply in the absence of a choice-of-law clause, nothing in clause 15.1 deprives you of the protection of those mandatory laws (Regulation (EC) 593/2008 “Rome I”, Article 6).

16. Dispute resolution

16.1. Consumers in the EU / EEA / UK

(a) We will endeavour to resolve complaints amicably. Please contact us first at contact@performanceturbo.eu.

(b) EU Online Dispute Resolution (ODR) platform. The European Commission provides a platform for online dispute resolution at: https://ec.europa.eu/consumers/odr

You may use this platform to resolve disputes out of court. Our email for ODR purposes is contact@performanceturbo.eu.

(c) You may also bring proceedings in the courts of your country of residence. We may only bring proceedings against you in the courts of your country of residence.

16.2. Business Customers (B2B)

(a) For disputes between us and a Business Customer, the courts competent for our registered office in Rybnik, Poland have exclusive jurisdiction, without prejudice to mandatory rules of international law.

16.3. Consumers in the United States – binding arbitration and class-action waiver

PLEASE READ THIS CLAUSE CAREFULLY. IT AFFECTS YOUR LEGAL RIGHTS.

(a) This clause 16.3 applies only to Consumers with a delivery address in the United States.

(b) Any dispute, claim, or controversy arising out of or relating to your Order, these Terms, or the Products (“Dispute“) will be resolved by binding individual arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules. Judgment on the award may be entered in any court of competent jurisdiction. The seat of arbitration shall be New York, New York, USA (or, at the Customer’s election, their state of residence). The arbitration shall be conducted in English. The parties each bear their own costs except as the arbitrator may award.

(c) CLASS-ACTION WAIVER. You and we each agree that any Dispute shall be brought only in an individual capacity and not as a plaintiff or class member in any purported class, collective, consolidated, or representative proceeding. The arbitrator has no authority to join or consolidate claims or to preside over any form of representative or class proceeding.

(d) Carve-outs. The following are not subject to arbitration and may be brought in a court of competent jurisdiction:

• claims seeking injunctive relief to protect intellectual-property rights;
• small-claims actions that qualify for the jurisdiction of a small-claims court;
• any claim that cannot be arbitrated as a matter of law.

(e) 30-day opt-out. You may reject this arbitration clause by sending written notice to contact@performanceturbo.eu within 30 days of your first Order, with the subject line “ARBITRATION OPT-OUT”. Opting out will not affect any other provision of these Terms.

17. General

17.1. Severability. If any provision is held unenforceable, the remaining provisions continue in effect, and the unenforceable provision will be replaced with an enforceable provision that most closely reflects the parties’ intent.

17.2. No waiver. Our failure to enforce any provision is not a waiver of that provision.

17.3. Assignment. You may not assign your rights or obligations without our prior written consent. We may assign our rights and obligations to any successor in our business.

17.4. Entire agreement. These Terms, together with the other policies referenced herein and any order-specific documents, constitute the entire agreement between us and supersede any prior communications on the same subject.

17.5. Changes. We may update these Terms from time to time. The version in force at the time you place an Order governs that Order. Changes become effective on the date they are posted on the Site.

17.6. Electronic communications. You agree that we may communicate with you electronically (email, Site notifications, and, where you have opted in, SMS), and that such communications satisfy any legal requirement of writing.

17.7. Language. These Terms are provided in English [and Polish]. In the event of a conflict between language versions, the [Polish] version prevails for Customers in Poland, and the English version prevails for Customers outside Poland.
