Overview

The Blox Racing CEL Fix is a check engine light eliminator adapter designed to resolve O2 sensor codes. It spaces the O2 sensor out of the main exhaust flow, preventing excessive heating while still allowing accurate readings.
Show original supplier description
The Blox Racing CEL Fix is a universal O2 sensor extender designed to eliminate check engine lights that may occur when using test pipes or when a catalytic converter is removed. This adapter spaces the O2 sensor away from the direct exhaust stream, which is often the cause of O2 sensor codes due to increased exhaust temperatures. By positioning the sensor correctly, it ensures proper reading of exhaust content without being overly exposed to heat. Constructed from high-grade plated steel, this CEL eliminator features an M18x1.5 thread pitch and is designed to thread directly into the existing O2 sensor bung. The O2 sensor then threads into the CEL eliminator itself. It is sold individually, but note that vehicles such as the 350Z, 370Z, G37, and G35 typically require two adapters for full functionality. Installation is straightforward, involving screwing the adapter into the exhaust and then screwing the O2 sensor into the adapter. However, it is important to confirm clearance before ordering, as certain vehicle, transmission, and test pipe/catalytic converter combinations may not provide sufficient space for the O2 sensor to be spaced out properly.
