The latest Cold-Air Intake System kit for the current 'B9' Audi S4, RS4 and S5, RS5 enables cold, dense air from outside the engine bay to reach the fuel metering unit more efficiently for great power gains.

The High-Flow TriFoam™ triple-layer construction is simply the best filtration material on the market, handmade in the UK and is the key to the power gains achieved.

The intake uses a clever design which retains the original Audi lower box of the intake, adding in a replacement lid, TriFoam™ filter and front intake scoop in matte carbon fibre.

It's not just about the performance; the beautiful carbon weave of the intake will enhance the engine bay every time you lift the bonnet.
