Product Description

When installing a high flow catalytic converter on your car or truck your check engine light (CEL) may illuminate due to an increase in airflow. An oxygen sensor spacer spaces out the rear oxygen sensor from the path of exhaust gases. This tricks the vehicle’s ECU into thinking that factory catalytic converter is still in place. There is NO GUARANTEE this will prevent a CEL on your vehicle because modern ECUs are very complex and rely on a variety of factors to determine if the catalytic converter is working properly.


FITS ALL STANDARD OXYGEN SENSORS – Most modern vehicles are fitted with M18x1.5mm threaded oxygen sensors. This spacer kit features M18x1.5mm threads allowing you to screw your oxygen sensor into the spacer and then the spacer into your exhaust.

Easy Installation: Straight bolt-on, no modification needed. Very easy to install.

A must need for any off-road vehicle running a high flow cat, sport exhaust, down pipe or a straight pipe.

Made by High polish steel: Durable corrosion resistant plating.

Thread: M18 X 1.5

Materials: Steel with Nickel.

Available Size: Length 32mm/1.26Inch.
