These are a popular upgrade for the failing stock actuators and aftermarket actuators found on many turbos manufactured for the 2.7T. These will work on hybrid k04 and k04/rs6 with slight modifications. They come with all available spring options so you can pick out what wastegate pressure works best for your goals / turbo.

Please note that this piston design is very particular about alignment and if your turbos don't come correctly clocked (most do not and cannot be clocked correctly without modifications unlike our house brand) the actuators will bind and not function correctly.

When purchased through us we offer support to ensure installation is correct.
