No dates were ever given and many said it would never happen, but APR is proud to release the K04 upgrade kit for the transversely mounted VW's. APR's kit includes the K04 turbo, the compressor inlet O-ring, four turbo to downpipe studs, one manifold to turbo gasket, 4bar fuel pressure regulator, and one turbo to downturn gasket. This kit is a straightforward 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 Turbo-Back Exhaust, the kit made 242hp/268lb-ft on 91 octane gas, and 245hp/275lb-ft on 93 octane gas. Although the exhaust is not required, it is highly recommended.

If you are currently an APR Stage I or 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 or II customers for $199 or $699 for new customers.

With the addition of an upgraded intercooler and APR Turbo Inlet Hose, we here at NGP have seen between 215-222whp on this K04 kit. (around 252-258 crank horsepower) Please note that certain models may need fine tuning with APR V-tune when using a turbo inlet hose. Please email with any questions.

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. 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.
