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. Owned by a BMW enthusiast, aFe power is recognized the world over as a leader in quality performance products for your BMW.

This is a drop-in stock replacement aFe performance air filter that installs into your BMW's factory airbox. This particular filter fits the following BMWs:


E31 8 series: 840i 840ci 1991-1999
E32 7 series: 740i 740il 1993-1994
E34 5 series : 530i 530i Wagon 540i 1993-1995
E34: M5 1991-1993
E39: M5 2000-2003
E53 X5 : X5 4.4i 4.6is 4.8is
Z8 : Z8

This version has an oil-free filter media for less maintenance. For the best flowing filter, with the best performance gain, we always recommend the standard aFe "Pro5R " filter (which has a blue pre-oiled filter media), but this oil-free filter flows only slightly less than the blue Pro5R style aFe filter, and requires no re-oiling after cleaning the 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.

Looking to make loads of power on pump gas? Enter: water/methanol injection. Regardless if you're tuned for conventional pump gas, E85, or race fuel, use of a properly configured and integrated water/meth system will reduce temperatures, allowing you to make more power than on just conventional fuel alone. Select your engine-specific nozzles (which are standard 1/8" NPT and install in most aftermarket chargepipes), your tank to mount in the trunk, upgraded steel braided lines if you so choose, and some boost juice and you just need a management solution! Optionally, add a BMS FSB for JB4 integration!

With CNC machined serviceable/cleanable nozzle inserts for precise fluid metering. Choose single or dual nozzles and match the flow rate to your power needs! ​Water/Methanol Injection (WMI) nozzles are determined by the intended power and how many bungs your charge pipe has. These nozzles are 1/8” NPT and screw in to bungs included on most aftermarket charge pipes. BMS "super atomizing" nozzles are designed and manufactured by BMS and are known for their great atomization and flow characteristics. The number on the methanol injection nozzle represents the approximate gallons per hour of fluid when at full flow. Generally speaking running two smaller nozzles is preferred to one larger nozzle for an equal flow to improve fluid atomization and distribution.
