Fits great and well made.
Only needed one but it came with two, so changed both. Great value and perfect match.

Generic 02 sensor
Did not work with 2000 Tacoma pre runner 3.4l. installed and plugs did not match the sensor 1 bank 1. The downstream did match up but 2 days after installing light came back. Put Denso in both and no more code. So this was a waste to save a little I spent more.

No gaskets
Was surprised to find that gaskets didn't come with the part. Had to buy local which was another $25. Parts are working fine though.

Great for price
Check engine light came on for one of them when i first installed on my 98 2.7 Tacoma. Cleared it and hasn’t came back in a month. Absolutely cannot beat these for the price

Both the same plug
I purchased these for my wendy Toyota 4Runner 00 and the plugs are both the same. The O2 sensor towards the engine side has a different plug than the one towards the rear. It fits the one towards the rear but not the one towards the engine side. I don't know which one is downstream or upstream but one of them won't work. The company needs to change the description if they're going to sell two the same one.
