Oxygen Sensor Spacer with Cat

  • This clever little oxygen sensor spacer has a tiny catalytic converter inside it! It can be used to reduce the chance of Check Engine lights on older cars that have worn-out cats, or race cars that don't have them any more.

    How well this works depends on a lot of different variables, including sensor location, exhaust heat, and more. Your mileage may vary.

    Threads directly into the stock rear oxygen sensor bung, then the oxygen sensor plugs into the spacer. Use care when handling the oxygen sensor -- it is fragile and easily damaged.

    Fits all late-model cars. Choose from straight or right-angle styles.
