Mass Airflow Sensor Cleaner

Gumout® Professional Formula Mass Air Flow Sensor Cleaner safely cleans gas and diesel MAF Sensors restoring sensor functionality and engine performance. Overtime, dirt, pollen, oil and other contaminates build up on the MAF Sensor which leads to poor sensor performance. A clean Mass Air Flow (MAF) Sensor is instrumental in ensuring the optimal air-to-fuel ratio is delivered to the engine. To maintain optimal functionality, clean the MAF sensor when the vehicle’s air filter is serviced/replaced.
