K04-025/K04-026 Turbocharger

The BorgWarner K04-025 and K04-026 turbochargers are presented as the core components for an RS4 turbo upgrade, specifically engineered for Audi's 2.7T B5 S4, Allroad, and A6 models. However, it is crucial to note that K04-specific turbo inlet pipes are required to complete the installation. It is important to understand that these RS4 turbochargers possess the capability to generate significant boost and air volume, potentially overwhelming stock fuel systems and programming. Therefore, this product is explicitly stated as not being a complete turbo upgrade kit and will likely require supporting modifications to the fuel system and engine management. For 2003 and 2004 Audi A6 and Allroad 2.7T vehicles equipped with automatic transmissions, a different downpipe design is utilized. Installation on these specific models will require some modification. CTS Turbo also outlines Borg Warner KKK Turbocharger Warranty Claims. To be eligible, turbochargers must be installed by a professional repair facility, with a receipt detailing the installation date and vehicle mileage. Warranty claims also require a separate receipt from the professional facility detailing the date and mileage of failure, the reasons for failure, and proposed corrective repairs. Borg Warner reserves the discretion to replace defective units, but all associated labor costs for diagnosis and repair remain the owner's responsibility.
