AFE BMW Performance Intake Kits for BMW 5 Series E39 (1996-2003)

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 light 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 horsepower and torque, improving acceleration as well as throttle response.

aFe has reported gains as high as 25 hp and 35 lb/ft torque for these kits, depending on the application.

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 filters 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.

This part fits the following BMWs:

"Oil-Free" ProDry S Filter

This intake kit replaces the top-half of both your factory air boxes. It features two 3-angle aluminum velocity stack adapters, 1.6mm powder-coated steel heat shields, trim sealed to seal out hot engine air, two custom aFe brand cotton filters, all hardware, and installation instructions.

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.

By converting your stock intake air boxes, you are improving the most restrictive portion of your M5's intake system, increasing horse power by 10 hp, torque by 10 lb/ft, improving acceleration as well as throttle response.

10hp max gain, 10 lb/ft torque max gain
