Male threads thread into existing M18 x 1.5 O2 bungs, bolt-on, no cutting or modification of stock wiring like an electronic CEL FIX / MIL Eliminator.

Installation: This oxygen sensor restrictor should NOT be installed with the primary oxygen sensor (sensor before the catalytic converter), quick and easy installation with no modifications needed.

Application: This oxygen sensor restrictor CEL Fix/Fouler with adjustable gas flow inserts. (Check Engine Light), For off-road race/track use only, prevent CEL (CHECK ENGINE LIGHT) / MIL (MALFUNCTION INDICATOR LAMP) from illuminating when removing the stock catalytic converter.

When installing a high flow catalytic converter on your car or truck, your check engine light (CEL) may illuminate due to increased airflow. An oxygen sensor spacer places the rear oxygen sensor out of the path of the exhaust gases. An extension spacer only minimizes the chance of CEL. Some vehicles need their ECU reset if the CEL is triggered beforehand.

This product works on your specific application. This kit allows for a proper and customizable installation position. Our oxygen sensor extension kit is machine TIG welded for a precise fit. The threads have been precision cut for a proper seal to prevent exhaust leaks and maintain proper sensor readings.
