Universal O2 spacers with real precious metal Catalytic Converters lengthen the distance between the O2 spacer(s). We've taken our spacers a step further by having built-in catalytic converters to allow the ECU to properly read exhaust gas and perform at optimal performance.
Oxygen sensors can occasionally trigger a CEL on stock vehicles due to the new advances of technology and would require an O2 spacer to bring the vehicle back to equilibrium and allow the ECU to read exhaust gases within the proper threshold.
Two fitting options and the two-piece design allow for complete adjustment to get the best possible fitment and results.
