Regardless of statutory warranty claims, we offer a voluntary three-year warranty on our BAR-TEK® products and Turbo-Total brand performance turbochargers. This warranty covers defects in materials and workmanship. The statutory rights of the consumer ("warranty holder") remain unaffected by this warranty.
1. Commencement of the warranty:
The warranty takes effect from the date of purchase.
2. Exclusions from the warranty:
The warranty is void in the event of improper use and, in particular, in the following cases:
- Improper installation or maintenance.
- Opening the turbocharger or removing seals.
- Incorrect engine tuning, such as... B. due to excessive boost pressure or excessive exhaust gas temperature.
- Use of unsuitable or incorrect lubricants.
- Damage caused by the ingress of foreign objects.
- Leaks in the boost pressure system.
- Contaminants in the oil.
- Blocked engine ventilation.
- Increased exhaust back pressure.
- Inadequate dimensioning of the intake or other components.
- Theft, accidents, or flooding.
- Exceeding the maximum permissible turbo speed.
Our racing engines are excluded from the three-year warranty.
3. Warranty Claims:
In the event of a warranty claim, we have the right to either replace or repair the defective part. Claims beyond repair are not accepted. Claims by the warranty holder due to intentional or grossly negligent conduct on our part, our agents, or legal representatives, as well as claims for injury to life, body, or health, remain unaffected.
4. No Transfer of Warranty:
The warranty applies exclusively to the original purchaser. In particular, it does not apply in the case of resale or gifting.
5. Notification and Handling of Warranty Claims:
- Material and manufacturing defects covered by the warranty must be reported within the warranty period. The warranty claim must be reported in writing (e.g., by letter or email) within one month of its occurrence. The date of receipt of the notification by us is decisive for compliance with the deadline.
- If the repair or replacement is covered by the warranty, the customer bears the costs of shipping to and from the warrantor.
- In the case of a defect not covered by the warranty, the warranty holder bears the costs of the repair. In this case, we will inform the warranty holder and provide a cost estimate for the repair. The repair will only be carried out with the express consent of the warranty holder.

High-end stud bolt kit for the cylinder head for all 2.9L & 3.0L TFSI as in the Audi RS4 B9 & RS5 F5 or S4 B9 & S5 F5.
A MUST for all engines that run high boost pressure and for which ARP is still not stable enough! BAR-TEK® stud bolts have an internal hexagon for screwing in the studs. Due to a cone on the block side of the bolts, they do not support themselves on the thread flanks when tightening the nuts, but in the bore of the thread in the engine block. This support protects the threads during frequent assembly of race engines.
Up to 35% stronger stretch steel than ARP bolts.
incl. bag of Moly Paste
Tightening torque in three steps. Final stage 110 Nm.
