Product Number: 4073E
Contamination on mass air flow sensor elements — hot wires, plastics and rubber — causes inaccurate readings that affect engine management. BG Mass Air Flow Sensor Cleaner (4073E, 89ml) is specially formulated to clean all of these materials without sensor disassembly, restoring sensor accuracy. Spray directly onto MAF sensor elements per the product label.
BG MAF Sensor Cleaner evaporates quickly and completely, leaving no residue on the sensitive sensor elements. Simply spray directly onto the MAF sensor components to dissolve and remove contamination without requiring the sensor to be removed from the vehicle.
Suitable for all petrol and diesel engines fitted with MAF sensors. Use when MAF sensor contamination is suspected or as part of an air induction service.
Spray directly onto the MAF sensor elements. Please refer to the product label for full instructions. Apply as part of a routine induction service to maintain engine efficiency. Suitable for a wide range of petrol and diesel passenger vehicles and light commercial applications.
Delivered in 2–3 working days to mainland UK. 30-day returns on unopened items.

A. BG 4073 (89ml aerosol) cleans contamination off the hot-wire and plastic elements of mass air flow (MAF) sensors without disassembly. Restores sensor accuracy and the engine fuelling and performance that depend on it.
A. With the engine off, remove the MAF sensor from the intake duct. Spray BG 4073 directly onto the sensor elements per the can directions. Allow to dry fully before reinstalling. Do not touch the sensor wires.
A. Symptoms include long-term fuel-trim drift, intermittent rough idle, hesitation under load, reduced fuel economy, or a MAF-related diagnostic trouble code. Cleaning is the first step before considering replacement.
A. Yes. BG 4073 is specifically formulated to clean hot wires, plastics, rubber and associated MAF sensor materials without damage. Generic carburettor or throttle-body cleaners are not safe for MAF sensors.
A. No — use BG 406 for throttle bodies and BG 4073 for MAF sensors. The formulations and applications are different. Using MAF cleaner on a throttle body is wasteful; using throttle-body cleaner on a MAF damages it.
A. Yes — MAF contamination typically returns over time, especially with aftermarket oil-treated air filters that contaminate the sensor. Re-clean periodically; if cleaning no longer restores function, the sensor itself has failed.
A. We accept returns within 30 days of purchase for items that are unused, undamaged, and in their original packaging. Returns are available only for UK-delivered orders and must include proof of purchase. Before returning an item, please contact us at [email protected] to obtain a Return Merchandise Number (RMN).
