O2 sensor adapter/flange for Toyota applications

Description

While most oxygen sensors use an M18 threaded mount, many Toyotas from the ’80s through the early ’90s used a two bolt flange to install their O2 sensors. Our Toyota style adapter flange allows you to swap in a wideband oxygen sensor without welding in an extra bung; Matches the factory bolt holes and outline exactly. This flange has the bolt holes 44 mm apart (center to center) and fits many popular Toyota models, including MR2s, most Supras, many 4Runners and pickups, and many others. If your factory O2 sensor mounts with two bolts instead of threading into the pipe, this is what you need to install a wideband.
