Note
Check Engine Light fix is achieved by spacing out the O2 sensor so it reads some exhaust gases but is removed from the direct flow. This tricks the ECU into detecting a restriction (e.g., catalytic converter).
This spacer reduces the chance of CEL but some vehicles may require an ECU reset if CEL is already active. No guarantee it will work on all vehicles.
