Air Fuel Ratio Sensor

The air fuel ratio sensor is installed in the exhaust manifold or in the front exhaust pipe, before the catalytic converter. The job of the air fuel ratio sensor is to measure the oxygen content in the exhaust and provide feedback to the engine computer PCM so that it can add or subtract fuel. 

Maxpeedingrods oxygen sensors are designed with high quality materials that ensure improved performance and long lasting durability to boost the optimum capacity of your car and improve the fuel efficiency of the vehicle.
