The JET Powr-Flo Mass Air Sensor delivers improved horsepower, torque and mileage from your car, truck or SUV by simply replacing the restrictive stock mass air sensor. The factory sensor not only is a major restrictive point in stock intake systems, but it also limits the full potential of aftermarket cold air intake systems. The flow bench tested design of the JET Mass Air Sensor provides airflow increases of up to 45 percent and installs in 10 minutes or less. Compatible with other aftermarket upgrades such as computer upgrades, cold air intakes, TBI spacers, free flow exhaust systems, etc.
