This part is listed as Bosch part number 0280217809 (0 280 217 809) and is described as the larger 3.5" HFM for 1996-2000 E36 M3 and MZ3 S52. The original application for this part is a Porsche 993 911 Turbo but the fitment and tuning makes it ideal for use in OBD-II E36 M3 and MZ3.

This larger HFM (MAF) is commonly used for tuning and increasing intake flow on S52 engines. It has a 3.5" diameter, as opposed to the stock US HFM (MAF) which has a 3.0" diameter. The larger HFM also has a greater resolution for reading airflow, which means fuel and timing corrections can be more precise.

Required: larger 3.5" air filter/intake, 3.5" throttle body boot, wiring harness adapter, OBD2 wiring harness and ECU, appropriate software tune, and many applications require higher flow fuel injectors.

This is an OEM HFM manufactured by Bosch - the original supplier to Porsche and BMW for this part, as well as many other components. As the OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
