2005 E46 330i/ci (all) and 325i/ci Afe Intake Kit With Pro5r Filter
aFe Magnum FORCE Stage 1 Cold Air Intake System for BMW E4 6 330i and 330Ci, 2004-2005 325i/Ci with M5 6 SULEV engine. Also fits X 3 3.0, 2004-2007. This intake kit replaces your restrictive factory air box. It features a 3-angle aluminum velocity stack adapter, 16-gauge powder-coated steel heat shield, trim sealed to seal out hot engine air, and a custom aFe brand cotton filter. 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- for only slightly less performance and no maintenance. 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. aFe has reported gains as high as 20 hp and 27 lb/ft torque on the 330i.
