Mass Air Flow Sensors

Mass Air Flow Sensors & MAF Sensors

The mass air flow (MAF) sensor measures the volume and density of air entering the engine, providing critical data to the ECU for accurate fuel injection and ignition timing calculations. A failed or contaminated MAF sensor causes poor fuel economy, rough idle, hesitation, and check engine lights. Replacing a worn MAF restores proper air measurement and engine management accuracy.

OneFastShop carries mass air flow sensors including OE-replacement MAF sensors, performance MAF housings, MAF sensor cleaning kits, and direct-fit replacements for popular engine platforms.

Every MAF sensor at OneFastShop ships brand-new with manufacturer warranty coverage. Whether you're replacing a failed MAF sensor, upgrading to a larger MAF housing for more airflow, or restoring proper air metering, OneFastShop has the sensor. Shop the full mass air flow sensors collection today.
