OEM GM Oxygen Sensors
The oxygen sensor in your vehicle measures the amount of oxygen in your exhaust gas in order to determine the amount of air needed for the fuel injectors, which gives you optimal performance and fewer emissions. It measures the air-to-fuel ratio and sends the information to the computer where adjustments are made. A bad oxygen sensor can cause your engine to run too rich or too lean. If you notice a rough idle or the check engine light on, replace your oxygen sensor with an OEM GM oxygen sensor.
- An OEM oxygen sensor will be optimized to meet the needs of your vehicle. It will know the right amount of fuel to air.
- An OEM oxygen sensor will last as long as the original part.
- OEM oxygen sensors are designed to be exact fit replacement parts that never need to be modified in order to get them to fit.
