Tune Your BMW for High Performance

Based in the Motor Valley of Italy, BMC Air Filters has equipped racing champions across Formula 1, Le Mans, Word Rally, DTM, and more. The expertise accumulated in the racing world by leading Italian engineers is directly transmitted to BMC’s production of aftermarket performance filters for the tuning market, available from Official BMC Dealers in Southern Africa.

Upgrade BMW M2, M3, M4, M5, M6 engine performance to new heights with the BMC High Performance Air Filter, the FB647/20. This sports cotton filter travels beyond the stock paper filter, providing modern filtration technology with a wider surface area that ensures your BMW breathes air at greater volume, leading to greater combustion for boosted performance.

The optimised air-to-fuel ratio unlocks heightened throttle and rev responses, alongside savings to fuel economy. And because the air fed into the engine is far cleaner (BMC cotton filters out contaminants up to 10 microns in size, whilst paper stops at 7 microns), there is decreased wear of engine components.

FAQ & Summary: BMW Replacement Air Filter – BMW M2, M3, M4, M5, M6

Q. How many engine air filters are required for the BMW M2/M3/M4/M5/M6?

A. Two. These vehicles have two engine air filters which are shaped differently to each other. If you are purchasing a BMC Air Filter, the code “FB647/20” refers to both air filters, packed as a pair in one box.

Q. What is the installation time and complexity for the FB647/20 filter?

A. Maximum 10-15 minutes per air filter. These are ‘drop in’ panel filters, so the process is easily DIY. No modifications required.

Q. Will the BMC FB647/20 fit all BMW M2, M3, M4, M5, M6 models?

A. No. BMC replacement filters are made to fit the exact dimensions of the original BMW airbox, which may differ by specific engine and year. For example, BMW M2 and M3 models from 2022/2023 onwards uses the BMC FB01118 performance filter due to differing OEM airbox dimensions and shape. View the compatibility list above for a general idea on BMC FB647/20 compatibility. Contact us with your M-Series details. We will confirm the correct filter, and an authorized in-stock BMC dealer in Southern Africa (South Africa, Namibia, Botswana, Zimbabwe, Swaziland, Mozambique).

Q. What real-world tuning benefits are expected with this sports filter on BMW M2, M3, M4, M5, M6?

A. Guaranteed tuning benefits feature increased and enhanced engine high performance, improved throttle response, and improved revability. Secondary benefits are long engine service life, fuel savings, and cost savings (because BMC filters can be regenerated for the entire service life of the vehicle (and not replaced frequently like paper/foam alternatives)). Pure power gains (across HP and torque) are possible, but not guaranteed due to specific vehicle tuning parameters. View BMC cold induction kits for definitive HP upgrades.

Q. What is the BMC cabin/pollen air filter for the BMW M2, M3, M4, M5, M6 models?

A. BMC does not produce cabin/pollen filters for any vehicle. BMC specialises in high performance upgrades only.

Q. How can I buy a sports performance filter for the BMW M2, M3, M4, M5, M6 in Southern Africa?

A. Contact us with your location and we will refer you to an official BMC authorized, in-stock dealer near you.
