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.
