BMW E31 aFe Cold-Air Intake Kits
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.
Bring your aFe filter back to life with a Restore kit from aFe. Included is filter cleaner & replacement oil. These air filter oils is designed to not harm MAF sensors, while allowing the filter to catch as much debris as possible.
