AEM No-Weld O2 Sensor Mount - Universal - 1.75-2.0in Pipe
Fitting a wideband air/fuel ratio sensor usually means dragging out a welder, but AEM's No-Weld O2 Sensor Mount skips that step entirely. It uses an integrated bung and clamp style design so you can mount a UEGO sensor with nothing more than a drill and the supplied hardware, making it a handy option for anyone building or tuning a custom exhaust.
This listing covers the universal No-Weld O2 Sensor Mount sized for 1.75-2.0 in (44-51 mm) exhaust pipe diameters, suiting most aftermarket downpipes, mid-pipes and test pipes within that range. As a universal fitment, it isn't tied to a specific make or model.
