Most Subaru vehicles rely on input from the Mass Airflow (MAF) sensor to detect the amount of air flowing into the engine.

Most Subaru vehicles rely on input from the Mass Airflow (MAF) sensor to detect the amount of air flowing into the engine. The input from this device directly affects drivability, fuel mileage and emissions. Dirt and oil can contaminate the MAF sensor affecting input the computer receives, altering the engine's performance. Periodic cleaning of the MAF will keep the engine running at peak efficiency.

Features:

• Quick, sensor safe
• Maintain proper air / fuel ratio
• Improves drivability
• Restores loss performance
