Maximum Flow Pro5R Filter
This intake kit replaces your restrictive factory air box. It features 1.6mm powder-coated steel heat shield, trim sealed to seal out hot engine air, and a custom aFe brand cotton filter.
By removing your stock intake air box, you are removing the most restrictive portion of your M3's intake system, increasing both horse power and torque, improving acceleration as well as throttle response.
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.
12 hp gain at 4900 rpm!
11 lb/ft torque at 4900rpm!
This aFe intake fits the following BMWs:
E46 3 series: M3 Coupe, M3 Convertible
This Torque Booster tube is a great upgrade to your Stage 1 air intake, and can even be used to upgrade your factory intake system. Constructed of 3-ply silicone, it's smoother for less turbulence and more durable for less maintenance.
Since 1999, aFe (Advanced FLOW Engineering) has been developing and manufacturing high quality accessories in their facility in Corona, California. Starting with air filters and intake systems, and now expanding into exhaust systems, suspension components, tuning modules, and more, aFe products are a great way to improve the performance of your BMW without altering its fundamental character.
