APR is now proud to release our K04 upgrade kit for the B6 Audi A4 1.8T. Our kit includes the K04 turbo, the compressor inlet O-ring, three turbo outlet studs, one manifold to turbo gasket, four Bosch fuel injectors, and one turbo to cat gasket. This kit is a straight forward turbo swap that makes a big difference in the power output of the car. This kit makes solid gains in both horsepower and torque. With no other mods than an exhaust, the kit made 247hp/286lb-ft on 93 octane gas. The exhaust is not required. This kit includes software. Injectors sold separately.
Legally, a vehicle manufacturer cannot void the warranty on a vehicle due to an aftermarket part unless they can prove that the aftermarket part caused or contributed to the failure in the vehicle (per the Magnuson Moss Warranty Act (15 U.S.C. 2302(C)).
