aFe Magnum FORCE Stage-1 Pro 5R Cold Air Intake System - E46 325i/Ci 330i/Ci, E83 X3 3.0i M54

Maximum Flow Pro5R Filter

This intake kit replaces your restrictive factory air box. It features a 3-angle aluminum velocity stack adapter, 1.6mm 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-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 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

For the maximum benefit in performance, we recommend upgrading your engine software with the Shark Injector (Click here for more info on the Shark Injector performance software.)

2003-2006 E46 3 series: 325i 325ci 325xi + Wagon & Convertible models with M56 engine
2001-2006 E46 3 series: 330i 330ci 330xi + Convertible

Want an extra layer of defense? Add a pre-filter to prevent water, mud and sand from congesting your air intake system. This simple upgrade slides over the aFe filter of this intake kit, much like a sock, giving you an extra layer of defense, and extending the cleaning interval of your aFe intake's filter element. Best of all, using the Pre-Filter does not significantly diminish your air filter s performance the smooth rush of oxygen keeps rolling right into your engine. To add the pre-filter, just select the option for the drop-down option below.
