What’s so special?
Our 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.
- Our High-Flow TriFoam™ triple-layer construction is simply the best filtration material on the market, and is the key to the power gains achieved.
- Each filter is handmade in the UK.
- 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.
- By reducing turbo spool by up to 500rpm in some cases through the enhanced efficiency of the system, lightning fast turbo response is guaranteed. In our experience, no other intake kit gives higher gains.
- It’s not just about performance; the beautiful carbon weave of the intake will enhance your engine bay every time you lift the bonnet!
