Maxiumum Flow Pro5R Filter

This intake kit replaces the top-half of both your factory air boxes. It features two 3-angle aluminum velocity stack adapters, 16-gauge powder-coated steel heat shields, trim sealed to seal out hot engine air, two custom aFe brand cotton filters, all hardware, and installation instructions.

This version uses aFe's highest flowing filter media, which uses a lightly oil gauze to filter out dirt and particulates, while allowing more air to flow to the intake. For the best flowing filter, with the best performance gain, we always recommend this standard aFe filter media (often called "Pro5R ", which has a blue pre-oiled filter media). We also carry this filter in the "ProDry" grey filter media, which is oil-free for only slightly less performance and no maintenance.

By converting your stock intake air boxes, you are improving the most restrictive portion of your M5's intake system, increasing horse power by 10 hp, torque by 10 lb/ft, improving acceleration as well as throttle response.

10hp max gain, 10 lb/ft torque max gain
