Eliminate many annoying error codes with our universal Oxygen Sensor Simulators

We searched high and low for a 02 Sensor Spacer that would weld on, and actually work!!! While no spacer works for every application, we now offer the same O2 Sensors Fabspeed utilizes on there systems for weld-on use.
These are recommended when using any test pipes, or high flow cats. We do not endorse these for use on street vehicles to repair or replace a functioning emissions system.

• Sold Individualy
• Note: generic image of  O2 spacer shown for example- (4) individual pieces are shown installed
