▶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.


The O2 CEL fixture actually incorporates the M18X1.5 miniature catalytic converter, which helps to get rid of the modified exhaust or the inspection engine light after removing the catalytic converter.

If the real catalytic converter is damaged, the CEL eliminator can reduce toxic gases;

If the O2 sensor is too sensitive, the CEL will still open after loading the canceller, and all problems on the CEL alarm will not be resolved. It can only solve one of the P0420 codes – Fault Catalytic Converter

  • WITH CATALYTIC CONVERTER – O2 sensor bungs mini catalytic converter

  • AVOID A CHECK ENGINE LIGHT – Catalytic converter built inside and will help get rid of that annoying check engine light.

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

  • 90 DEGREE bend design is great for spacer clearance issue.

  • CNC CUTTING – with steel material and plating Nickel
