(1 review) Write a Review

The O2 Sensor MIL Eliminator for the 1996-2004 Ford Mustang GT/Cobra/Mach 1 allow exhaust system modifications such as high flow cats, no cats, long tube headers, H and X pipes without triggering a Check Engine Light by simulating the oxygen sensor signal to the computer. In some cases, you may need to trim the tabs on the connector, but generally it'll snap into place.

    Works great, easy to install

    I live in Canada. Have a '97 Mustang GT 4.6L. After i put on my cat less exhaust the check engine came on and computer runs in safe mode which hurts performance. This product removes the check engine light and restores power back to normal. Very easy to install. On a hoist 2 minutes.
    Also want to thank OBD for the speedy delivery.
