The Porsche HFM/Mass Air Meter is a 3.5" diameter Bosche mass air meter for direct plug-in for 96+ E36 M3 and MZ3 cars. This item includes one mass air meter only, with no adaptors, hardware, fuel injectors, cams, or software included - these are typically required when upgrading and can be purchased separately or as a kit elsewhere on this site.

This 809 version of the Porsche/Bosche air meter is typically used in combination with Conforti Shark Injector software. (The 803 version used with BimmerWorld software, as well as many others on the market, is available also.)

This mass air meter DOES NOT make additional power when installed on its own, but when used WITH additional performance parts, it does allow proper metering of intake air.

Please contact us for additional information on a proper combination of components for your car. These electronic parts are not returnable and you are responsible for choosing the correct air meter for your application.
