Universal Mini Catted O2 Spacer(s) 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 Catalytic Converter(s) or Test Pipes (DeCats) are 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 Cat / Test Pipe. These are offered in 3 different types, Straight, 45 degree, and 90 degree and are easier to adjust for sensor placement. *These are sold individually* Show more
