Product Details

If your turbochargers have reached the end of their life or you're just looking for a performance upgrade, ECS Tuning has put together the ultimate kit just for you. This kit allows you to upgrade to the more durable and higher performing turbocharger setup found on the European RS4 2.7T. This kit does not include the oil return lines or hardware, and it is recommended that they be replaced with the turbocharger.

This setup does not include the RS4 or modified intake pipes to complete installation, must be purchased separately.  For a bolt-on solution, please see 034Motorsport's inlet pipe kit 034-145-P002 (ES2864575). 

*RS4 turbochargers have the ability to produce too much boost & air volume for your stock fuel system & programming. This is not a complete turbo upgrade kit*

*2003 and 2004 A6 and Allroad 2.7T's with automatic transmissions have a different downpipe design, and some modification is required for installation.*

 

*ECS Tuning's Official Policy regarding Borg Warner KKK Turbocharger Warranty Claims*

To be eligible for warranty consideration, Borg Warner has stipulated that KKK turbochargers (or turbocharger kits) must be installed by a professional repair facility.

  • Warranty claims must be accompanied by a receipt from a professional repair facility showing the date and vehicle mileage when the turbocharger was originally installed.

  • An additional receipt from a professional repair facility must accompany the warranty claim indicating:

1. Date and mileage at which the turbocharger failed

2. Reasons for turbocharger failure

3. Proposed repairs intended to correct the cause of the failure (if any).

Borg Warner will, at its discretion and with proper documentation, replace a turbocharger that has failed due to defects in materials and/or original workmanship. All associated labor charges for diagnosis and repair are the responsibility of the vehicle owner.
