The Liqui Moly Air Flow Sensor Cleaner is a specialised fast-acting solvent developed for the safe and effective cleaning of sensitive air flow sensor components in both petrol and diesel engines. Designed to clean hot wire and hot plate sensors, it removes contamination that can cause incorrect airflow readings and disrupt the fuel-to-air mixture. This cleaner evaporates rapidly without leaving residue, ensuring delicate sensor elements remain undamaged. Restoring a clean sensor helps improve starting behaviour, idle stability, engine performance, and fuel efficiency. On vehicles with automatic transmissions, it can also help prevent shifting problems linked to faulty airflow readings. Regular use can often eliminate the need for costly sensor replacement.
