M18*1.5 S/S Eml Light O2 Oxygen Sensor Extension Spacer

The M18*1.5 S/S EML Light O2 Oxygen Sensor Extension Spacer is an effective solution for preventing check engine lights triggered by exhaust modifications. Designed with a built-in mini catalytic converter, it helps correct post-O2 sensor readings, preventing error codes like P0420 (Catalyst System Efficiency Below Threshold Bank 1) and P0430 (Catalyst System Efficiency Below Threshold Bank 2).

Made from high-quality stainless steel (S/S) and featuring an M18 x 1.5 thread size, this extension spacer is built for durability and reliability. Its simple plug-and-play installation allows you to quickly resolve CEL issues without complex tuning or ECU modifications.

Ideal for off-road use, this spacer ensures smoother engine operation by maintaining the correct O2 sensor data, reducing false emissions warnings caused by increased airflow or temperature changes. If you’ve modified your exhaust system and need a dependable fix, this O2 sensor extension is the perfect solution.
