B6 A4 1.8T K04 Turbo Upgrade
Many said it would never happen, but 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 to downpipe studs, one manifold to turbo gasket, four Bosch fuel injectors, and one turbo to cat gasket. This kit is a straightfoward 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 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.
K04 Turbo & Injectors
The software for this kit is also available separately.
