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.
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.
APR now REQUIRES the purchase of an oil/filter & coolant kit with your turbo...Please see required lubricants for your options
