The factory intake simply can’t match the performance of ours. The factory system flows a maximum of 400 CFM at 28” in of H2O. We improve this by 31% as our full intake system flows 525 CFM!
We’ve reduced pressure drop across the system and improved turbocharger efficiency. The turbo spools faster, and operates in a more efficient region of the compressor map. This directly translates to more power and torque you can feel. On our Stage 1 (93) S4 we saw an improvement of 19 AWHP and 20 AWFT-LBS of torque simply by installing our intake system!
