Show original supplier description

The Prosport Mini Cat 02 Sensor CEL Fix is engineered to resolve check engine lights (CEL, SES, DTC) that may arise after exhaust modifications or catalytic converter removal. This small, 90-degree angled adapter contains a miniature catalytic converter that tricks the ECU into believing the stock catalytic converter is still in place, preventing error codes like P0420 and P0430. Constructed from steel with a zinc-plated finish, this O2 sensor extension features a M18 x 1.5 thread and is designed for an 18 ft-lbs torque specification. The universal application means it fits most makes and models, though some adaptation may be required. It is specifically recommended for 4-cylinder boosted engines or 6-cylinder engines; larger sizes are available for more demanding applications. This product is intended for off-road use only and is sold individually. Installation is described as simple, typically taking approximately 30 minutes.
