Product Number: MAF-144
The MAF-144 is a Mass Air Flow (MAF) sensor designed as a direct-fit replacement for BMW petrol applications equipped with the M54 and M54226S1 engine families, spanning the 2000 to 2005 production period. The sensor measures the volume and density of air entering the engine, supplying the engine management system with the data required for accurate fuelling and combustion control.
As a precision-engineered replacement component, the MAF-144 is built to restore correct air-mass measurement after the original unit has degraded or failed. Accurate MAF sensor output is critical for maintaining fuel efficiency, smooth idle, and responsive throttle behaviour - symptoms of a failing unit typically include rough running, increased fuel consumption, and fault codes relating to the air-fuel mixture.
The MAF-144 covers seven confirmed BMW applications across four model lines: the 3 Series (E46) saloon, Convertible, Coupé, and Touring - all fitted with the M54 256S5 2.5-litre engine - as well as the X3 (E83) 2.5i and the Z4 (E85) 2.2i. Year coverage runs from September 2000 across these variants. Cross-reference data confirms compatibility against 13 OE and aftermarket part numbers, including BMW 13 62 7 513 957, BMW 13 62 7 566 984, ERA 558153, Fispa 38.803, Fuel Parts MAFS388, Hoffer 7516181, Lucas FDM935, Mapco 42664, Meat & Doria 86181, S.I.D.A.T. 38.803, Siemens VDO A2C59511576, VDO A2C59511576, and Vemo V20-72-5143.
The MAF-144 is supplied as a single replacement sensor unit. Country of manufacture is shown on the product listing.
