This is actually two pieces; a threaded sensor and a bracket with two holes that fit my 4Runner . More honest photos would have show the two pieces . One should be very careful to fully tighten the sensor into the bracket as the extreme heat and then cooling of the exhaust in that location might tend to cause the fit to loosen . A one piece sensor is what your original was and also what I would’ve preferred to buy . It did cause the CEL light to go out after disconnecting the battery for several minutes to clear the old code. It is working for now .

Worked as described on 2002 Toyota 4Runner. Check engine light turned off once installed. Saved a lot of money purchasing this through Amazon. Don’t forget to get the gasket. It is not included.
