Fits 1995-1999 BMW M3 Base and Lightweight models. This aFe MagnumFORCE AIS coupling reducer is specifically engineered to allow the installation of a high-performance Euro-spec MAF sensor onto the US-domestic market (USDM) E36 M3 throttle body.

Constructed from 100% polyurethane for superior durability and heat resistance, this adapter features an integrated stainless steel sleeve within the neck. This reinforcement provides essential rigidity, preventing the coupling from collapsing or distorting under heavy clamping loads or engine vacuum. The inlet diameter measures 88.9mm (3.5 inches) to match the Euro MAF, reducing down to 71.1mm (2.8 inches) for a precise fit on factory USDM throttle bodies.
