OEM GM Oxygen Sensors

Refine Results

The oxygen sensor measures the air-to-fuel ratio. 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, it is time to investigate (details on that here). If you need to replace your oxygen sensor, only do it with a genuine 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.

When you buy your OEM GM parts from us, you get our no-hassle return policy, as well as our VIN verification to ensure order accuracy. Shop for your new GM parts today.
