This is the ultimate intake upgrade for the Audi RS4 and RS5 (B9). It flows 36% more than stock, reduces pressure drop, and improves linearization across the turbos. This directly translates to +19 AWHP and +17 AWFT-LBS of torque on top of our Stage 1 (93) tune making this a simple upgrade for more power you can feel. ull intake system: Inlet, airbox, filter, and inlet piping +19 AWHP & +17 AWFT-LBS measured over stock (APR Stage 1 93) Flows 36% more than stock Reduced pressure drop at the turbo inlets Improved linearization across the turbos Enhanced engine sound Carbon fiber construction Turbos spool faster Turbos operate more efficiently Massive 7” x 7” filter with a 4” outlet and 5.5” frontal inlet High flow and washable pleated cotton gauze filter material Airbox has additional flow paths faced away from the engine Inlet piping diameter is maximized from the 4” filter all the way to the turbochargers Inlet piping addresses system restriction, unlike competitive airbox systems
