APR B6 A4 1.8T K04 Turbo Upgrade
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 98 octane fuel. 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.

Part of the APR Turbocharger System install process requires removal of the OEM Turbocharger. During this process, oil and coolant must be drained and should be replaced to offer superior performance and protection. The APR Turbocharger Systems are now complete turn key solutions, including everything you need down to the oil, coolant and oil filter. During checkout you'll be given the option between Motul Specific 502.00, 505.00 & 505.01 5W40 or Motul Power 300V engine oil as well as Motul Inugel Optimal Ultra Coolant and an OEM oil filter.
