AEM No-Weld O2 Sensor Mount - Universal - 2.25-2.5in Pipe
Fitting a wideband air/fuel ratio sensor shouldn't mean firing up a welder. AEM's No-Weld O2 Sensor Mount uses an integrated bung and a simple drill-and-clamp installation, giving you a clean, leak free sensor bung without any exhaust fabrication work. It's a practical solution for anyone adding a wideband UEGO sensor to their exhaust system without access to welding gear.
This listing covers the mount sized for 2.25 to 2.5 inch (57-64mm) exhaust pipe diameters, suiting most aftermarket cat back and mid pipe sections in this range. As a universal fit component, it isn't tied to a specific make or model, so check your pipe's outside diameter before ordering.
