90-degree O2 CEL Fix V2 Adapter

The Circuit Werks 90-degree O2 CEL Fix V2 Adapter is a specialized component designed to address the Check Engine Light (CEL) that often illuminates after installing aftermarket downpipes or cat delete pipes. By precisely spacing the secondary oxygen sensor, this adapter effectively tricks the vehicle's Engine Control Unit (ECU) into believing that the catalytic converter is still functioning correctly, thereby preventing the CEL from triggering. Constructed with an M18x1.5 male thread to connect directly into your O2 bung port, it also features an M18x1.5 female thread to accommodate most common oxygen sensors. This Version 2 of the adapter has been engineered for a better success rate in preventing CELs compared to earlier iterations. It is important to note that while this adapter is highly effective, its compatibility can vary between vehicle ECUs, and it may not work on all applications. This product is intended for off-road vehicle use only. Installation involves threading the adapter into the exhaust system's O2 sensor port and then installing the O2 sensor into the adapter. Please consult your vehicle's specific manual or a professional if you are unsure about compatibility or installation procedures.
