APR T2100004 K04 Turbo Kit for Audi B6 A4 1.8T

APR is proud to release their K04 upgrade kit for the B6 Audi A4 1.8T. APR's kit includes the K04 turbo, the compressor inlet O-ring, three turbo to downpipe studs, one manifold to turbo gasket, and one turbo to cat gasket. This kit also includes the APR K-04 chip programming for the B6 A4 1.8t (a $699 value!). This kit is a straight forward turbo swap that makes a big difference in the power output of the car.

The APR K-04 kit makes solid gains in both horsepower and torque. With no other mods than an APR Exhaust, the kit made 247hp/286lb-ft on 93 octane gas. Although the exhaust is not required, it is highly recommended.

If you are currently an APR Stage I/I+ or II/II+ customer and purchase a K04 upgrade, you will receive all EMCS options for free. The software for this kit is also available separately for current APR Stage I/I+ or II/II+ customers for $199 or $699 for new customers.
