The oxygen sensor is a device which determines the oxygen content of the exhaust gas. Since the amount of oxygen in the exhaust gas is a very good indicator of combustion efficiency, it is also the best place to monitor the air fuel ratio. Our Oxygen Sensors are precision made for outstanding performance and manufactured to meet and exceed all original equipment specification and test requirements. Improved Engine Response & Performance Lower Emissions Improved Fuel Economy Longer Sensor Life Meets OEM Specifications .
