Racingline Performance Carbon Intake System - Audi S4 / S5 (B9)
 
Racingline's latest Cold-Air Intake System kit for the current 'B9' Audi 3.0 TFSI enables cold, dense air from outside the engine bay to reach the fuel metering unit more efficiently for great power gains.
 
Racingline's 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 itself uses a smart design that retains the original lower half of the factory Airbox adding in a replacement Carbon Fibre Lid, Tri-Foam filter and front Intake Scoop
Reduced turbo spool as much as 500rpm in some cases through enhanced efficiency, lightning fast turbo response guaranteed! 
Not only about performance but the beautiful carbon fibre weave of the intake's lid and scoop enhance your engine bay each time you lift your bonnet!
