Audi fanatics, this is the heart of the RS4 turbo upgrade for your B5 S4/Allroad/A6 2.7T. These RS4-K04's are a factory bolt on for the B5 S4/Allroad/A6 2.7T, they will bolt up to your downpipes/catalytic converters, and exhaust manifolds.
*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 Audi A6 and Allroad 2.7T's with automatic transmissions have a different downpipe design, and some modification is required for installation.*
