We recommend that you also install our harmonic vibration damper with gel filling directly at. This eliminates all negative vibrations that occur on the crank drive, also ensures improved idling and reduces turbo lag during fast gear changes. In order to be able to install the vibration damper optimally, you can also find our counterholder set for vibration damper and crankshaft here.

You should install our h-beam conrods for 4.0L TFSI engines from stage 4 at the latest. These are extremely light and stable at the same time, making them perfect for extreme performance.

The turbocharger is one of the most important tuning measures of all, as there is extreme performance potential in the compression ratio. That is why you will find all the turbos from the guides and suitable alternatives in this special turbo guide, for example if you prefer a specific manufacturer. We have also compiled a lot of information for you on the subject of turbocharger, which you should take a look at.
