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.
