aFe Cold-Air Intake Kits for BMW 3 Series E46 (1999-2005)

Clear BMW chassis
Founded in 1999, Advanced Flow Engineering (aFe) produces high flow, high performance replacement air filters and complete cold-air intake systems for BMWs. Each precision-engineered intake component and filter offers excellent design and construction, lifetime cleanable cotton filters that breathe easier than paper filters, powder-coated heat shields to block out hot engine air, and measurable performance gains resulting in increased horse power and torque. aFe's reputation is fast growing as a manufacturer and designer of quality and functional intake kits with excellent fit and finish and reasonable cost.

aFe enigneers their kits for each individual model application, even designing air filters from scratch to maximize the available surface area of the low pressure zone. They then offer their intake components in packages that fit your tastes and needs -
Replacement Performance Filter. A direct performance replacement filter for your stock air box.
Dynamic Air Scoops. Metal scoops or ducts that create a 'ram-air' effect to the intake.
Super Stock System. A performance filter combined with Dynamic Air Scoops and Throttle Body Spacer for power gains while keeping the OEM appearance.
Stage 1 Kit. A cone-filter kit with vehicle-specific heat shield and intake tubing to replace a stock airbox.
Stage 2 Kit. All of the components in a Stage 1 Kit plus additional intake tubing or ducting after the air box or air mass meter.
Sealed Intake. A Stage 1 or 2 Kit with an enclosed airbox and heat shield. The filter area is maximized inside a vehicle-specific airbox and then sealed with a cover for a OEM-type appearance.

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 Dynamic Air Scoop is constructed with lightweight aluminum for strength and finished off by a matte red powder-coated finish.

Hassle Free Installation:
All necessary hardware is included for an easy, hassle free installation.

Prevent water, mud and sand from congesting your air intake system with the aFe Pre-Filter. This aFe Pre-Filter slips right over your performance air filter, adding an extra layer of defense against moisture, grime and other roadway filth, extending the cleaning interval of your aFe filter. Water is repelled by the proprietary hydrophobic treatment to the Pre-Filter's polyester fabric, and the pre-filters uniformly spaced micron holes prevent debris .005" or larger from passing through. 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.
