5303 988 0146 - Borg Warner Airwerks Turbocharger SX K03 Upgrade K03-2074 MINI Cooper S EP6 HP - 41mm
Borg Warner Airwerks Turbocharger SX K03 Upgrade K03-2074 MINI Cooper S EP6 HP - 41mm
For those seeking a top-tier OE replacement upgrade turbo for their 1.6L car, the BorgWarner unit is the ultimate solution. It seamlessly replaces vehicles originally equipped with MINI Factory Borg Warner Turbochargers, offering an upgraded alternative for both the Cooper S and JCW models.
Keep in mind that the larger inlet necessitates an aftermarket intake system featuring a silicone hose or an aftermarket silicone intake hose to adapt to the larger inlet. Adjustments to factory inlet boots may be required for proper fitting.
With a piggyback tune, this turbo delivers power ranging from 225 to 255HP. With a more aggressive tune, you can push the limits up to 300HP. However, it's crucial to acquire a custom flash tune (not supplied) to prevent the turbo from backing off during full pulls.
Warranty claims for this turbo upgrade must be supported by a receipt from a professional repair facility, indicating the installation date and vehicle mileage. Additionally, a separate receipt from a professional repair facility should accompany the warranty claim, specifying the date and mileage of the turbocharger failure, reasons for the failure, and proposed repair solutions if necessary. Borg Warner will consider replacing a failed turbocharger due to material and workmanship defects, provided proper documentation is provided. Please note that all associated labor charges for diagnosis and repair are the responsibility of the vehicle owner.
