TT mk1 (1999-2006)
- 42 Draft O2 Sensor Spacer
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 new cat 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 used the exhaust gases are able to pass by the cat at a much faster rate, disrupting the readings. Our 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.
Our O2 Sensor Spacer is CNC machined from cold roll steel & grade 8.8 metric hardware. After assembly, our spacer undergoes a zinc dichromate plating process which protects the spacer from corrosion. Installation is plug & play. Simply thread in our spacer, thread in the rear o2 sensor, and lock the spacer at the desired angle.
