Product Number: MAF-057
The MAF-057 is a replacement Mass Air Flow (MAF) sensor designed to restore accurate air charge measurement across a broad range of Vauxhall, Opel, and Saab petrol-engined vehicles. Covering 34 vehicle applications across three makes and spanning model years 1993 to 2001, it is a direct-fit replacement for worn or faulty original sensors in applications such as the Opel Omega B 2.5 V6 (X25XE) and 3.0 V6 (X30XE), including both saloon and estate body styles.
The MAF-057 is supported by an extensive cross-reference list of 32 OE and aftermarket references, confirming broad interchangeability with parts from Bosch (0 280 217 519), Lucas (FDM723), Mobiletron (MA-B065), Quinton Hazell (QM735), Fuel Parts (MAFS051 / MAFS051-OE), and original equipment numbers from Vauxhall, Opel, and Saab (including 90530442 and 90541591), among many others.
As a mass air flow sensor, the MAF-057 provides the engine control unit with accurate data on intake air volume, enabling correct fuelling and ignition timing. A faulty sensor can present as poor fuel economy, erratic idle, reduced performance, or illumination of the engine management warning light. Fitting a correctly specified replacement is essential to restoring closed-loop engine management operation.
Vehicle coverage spans Vauxhall (16 applications), Opel (15 applications), and Saab (3 applications). Please verify fitment against your vehicle's make, model, engine code, and production date before ordering.

A. The mass air flow sensor measures the volume of air entering the engine and sends this data to the engine control unit so that fuelling and ignition timing can be calculated correctly. When the sensor fails or degrades, common symptoms include poor fuel economy, rough or erratic idle, reduced engine performance, and illumination of the engine management warning light. Replacing the sensor with a correctly specified unit restores normal closed-loop engine management operation.
