GMC Sierra Oxygen Sensor

Denso Oxygen Sensor - Any good mechanic will tell you use the very best products you can. DENSO First Time Fit oxygen sensors are specifically designed to meet the increasing demands of todays engines. Each of our oxygen sensors is constructed of the highest quality materials available. High-quality stainless steel, porous polytetrafluoroethylene (PTFE), fluorine rubber, aluminum oxide, high-grade platinum and ceramics are used in each DENSO oxygen sensor. DENSO produces the finest oxygen sensors in the world. How can we state this? Because, in many cases, we designed, tested, and manufactured the OE unit.

Delphi Oxygen Sensors - Delphi Switching Oxygen Sensors with planar element technology provide stoichiometric measurement of exhaust gases for gasoline engine and alternative fuel applications to help manufacturers meet current and future emissions standards. Delphi Switching Oxygen Sensors include a pumped air reference feature to prevent air reference contamination. They can be used in the engine-out position and in a post-converter location for more accurate engine control and for better exhaust system diagnostics.

Bosch Oxygen Sensors - Properly functioning oxygen sensors are important when it comes to your vehicle's fuel economy and reducing harmful exhaust emissions. That's why checking for, and possibly replacing, a worn-out oxygen sensor is an important part of every routine tune-up. And routine maintenance is more than just routine when you use Bosch Oxygen Sensors along with Bosch Spark Plugs as part of a Bosch Premium Tune-Up. You'l be helping the environment and saving money in gasoline costs over the life of the sensor.
