RacingLine Cold Air Intake Kit for B9 Audi S4 & S5 3.0 TFSI and RS4 / RS5 2.9 TFSI. Let your Audi breathe free with our beautiful new Carbon Cold Air Intake system for the V6 TFSI engine.

The highest-performing, race-bred cold-air induction intake for the B9 Audi RS4, S4 & RS5, S5

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

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
