Maxiumum Flow Pro5R Filter

This intake kit replaces your restrictive factory air box. It features 16-gauge powder-coated steel heat shield, trim sealed to seal out hot engine air, and a custom aFe brand cotton filter. aFe has reported gains of 27hp and 34 lbs/ft of torque.

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 removing your stock intake air box, you are removing the most restrictive portion of your 335's intake system, increasing both horse power and torque, improving acceleration as well as throttle response.
