OEM Bosch E36 M3 Euro HFM -- E36 M3 Z3

This Euro HFM (Hot Film Meter or mass air sensor) from the Euro M3 is larger in diameter than the USA's M3 meter. This HFM will meter and flow more air than the stock one, giving you more power. THIS REQUIRES PROPER SOFTWARE to run correctly and you may also need larger fuel injectors to prevent the engine from running lean.

We use this HFM on the 1995 M3 or any 1996+ S52 engine that has been converted to OBD-1 electronics. We prefer to use this HFM over the 540 meter because this is a direct bolt-on to the Euro airbox (for those that want a factory appearance). This HFM is not used on our OBD-2 Performance Kits or with OBD-2 Shark Injector software.

This is an OEM replacment (Bosch part # 0 280 217 806) for BMW part # 13621403123.
