Time to ditch your 30 year old archaic dinosaur two bolt sensor!
Designed to be a direct replacement for the Toyota OEM two bolt oxygen sensor. This is a standard M18x1.5 sensor threaded into a two bolt flange. You simply remove the sensor from the flange and thread it into your desired elbow or downpipe.
