42 Draft Designs - O2 / Oxygen Sensor Spacer
Newly re-designed and in stock, ready to ship!
When an aftermarket high-flow catalytic converter is used on a late model car it’s common to see a CEL (Check Engine Light) come and go. This CEL is usually backed by a fault code that indicates a failed cat. If your catalytic converter is NEW, how could it have failed? Behind the scenes, the factory ECU is comparing the readings from a pair of oxygen sensors to measure the effectiveness of the cat. When a high-flow cat is installed to your vehicle, the exhaust gases are able to pass through the cat at a much faster rate, which can disrupt the readings. The 42 Draft Designs o2 sensor spacer retracts the second oxygen sensor from the direct flow of gases, restoring the balance that the ECU requires when using a high-flow cat.
The 42 Draft Designs O2 Sensor Spacer is CNC machined from cold roll steel & grade 8.8 metric hardware. After assembly, the spacer is finished off with a high-polish finish for that extra touch. Installation is plug & play: Simply thread in the spacer, install the rear o2 sensor, and lock the spacer at the desired depth.
