The factory intake system simply can't match the performance of our intake system. The factory frontal airbox only flows 470 CFM at 28" of H2O. We improved this by up to 113% with our open airbox across the testing range and hit a peak flow of 935 CFM by at the same depression! This directly translates to more power you can feel. Our 1.5T test vehicle saw an additional and 10 WFT-LBS of torque and 6 WHP compared to stock! These are solid gains that make a noticeable difference in performance!
