Johnsen'S johnsen's mass air flow sensor cleaner 10oz

Johnsen’s Mass Air Flow Sensor Cleaner is specially formulated to safely and effectively clean sensitive mass air flow (MAF) sensors, restoring proper and improving overall engine performance. Over time, dirt, oil, and debris can build up on the sensor, leading to rough idling, poor petroleum economy, and reduced engine efficiency—this cleaner helps eliminate those issues quickly.

Engineered for precision, this fast-drying, residue-free formula removes contaminants without damaging delicate sensor components. Regular use helps maintain accurate airflow readings, ensuring smoother acceleration, better petroleum efficiency, and reduced emissions.
