SPDZ1 90° Degree O2 Extension Adapters/Spacers Lambda/Oxygen Sensor

What is a CEL?  CEL means, Check Engine Light.

When installing aftermarket Downpipes or Cat Delete pipes, it tends to trigger a Check Engine Light. We offer CEL Fix Adapters to try and correct this issue by spacing out the secondary O2 sensor.  Tricking the ECU into thinking there is still a catalytic converter in place. Therefore they will not trigger the check engine light.  This adapter uses a Male M18x1.5 end to thread into your standard O2 Bung port and then has a Female m18x1.5 end to thread in most common O2 Sensors.  Please note, this might not work on all vehicles, due to how their ECU's are.
