APR Audi A4 1.8T K04 Turbo Upgrade (2002-2005)

Many said it would never happen, but APR is now proud to release our K04 upgrade kit for the B6 Audi A4 1.8T.

The 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.

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.


ICS has done several of the APR K04 Turbo Upgrades for the B6 A4 1.8T and when Dyno Testing is performed, the average Wheel HP with a High Flow Cat and Cat Back Exhaust is in the area of 225 WHP.  Most often this system is used when the stock Turbo fails and the client just wants to get the vehicle back on the road without going back to the weak OEM K03 Turbo.
