Maxiumum Flow Pro5R Filter

This intake kit replaces your restrictive factory air box. It features a 16-gauge powder-coated steel heat shield, heat-resistant molded intake tube, trim sealed to seal out hot engine air, and a custom application-specific aFe brand cotton filter.

This version uses aFe's highest flowing filter - the Pro 5 R. This filter uses a 5-layer, lightly-oiled cotton gauze material to filter out dirt and particulates, while improving airflow through the intake. For the best flowing filter, with the best performance gain, we always recommend the oiled aFe filter over the dry versions. The Pro 5 R filter is washable and re-oiled using aFe's approved Restore Kit.

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