Universal O2 Spacers lengthen the distance between the O2 sensor(s) and the exhaust flow in order to minimize Check Engine Light occurrences.                    

The factory ECU compares the readings from a pair of oxygen sensors to measure the effectiveness of the catalysts. When a high-flow cat is used the exhaust gases are able to pass by the cat at a much faster rate, disrupting the readings. Our O2 spacers retract the secondary oxygen sensors from the direct flow of gases, restoring the balance that the ECU requires when using high-flow cats. The two piece design allow for adjustment to get best possible fitment and results. 

• Fits most makes & models worldwide
• Compatible with all Fabspeed Motorsport header, Sport Cat, and Catbypass products
• Minimizes the triggering of the CEL by moving the O2 sensor further from the exhaust stream.
• Male end threads into existing M18 x 1.5 O2 Bungs
• Two O2 spacers are included

IMPORTANT NOTES:

• For use on 2ndary Oxygen sensors sensors only!
• This product cannot guarantee emissions compliance or CEL lights BUT often cures issues
• Universal fitment
