Walker Products Oxygen (O2) Sensors are precision manufactured from premium components in an ISO 9001-2008/TS16949 certified facility. The oxygen sensor monitors the oxygen content of the exhaust gas, which is a very good indicator of combustion efficiency. The data collected is used to control the air fuel ratio through the engine control computer. The computer uses this information and other sensor inputs to calculate the correct amount of fuel delivered to the engine.

Walker Products Oxygen Sensors are designed to provide outstanding performance and are manufactured to meet and exceed all OEM (Original Equipment Manufacturer) specifications and test requirements. Walker Products specializes in the engineering, manufacturing, and distribution of automotive engine management components. Trust their award winning commitment to product quality when replacing the O2 sensor in your car, truck, van, Jeep, CUV (Crossover Utility Vehicle) or SUV (Sport Utility Vehicle).
