OEM part for an 06 Honda Accord. Worked once installed. Check engine light is now off. I did install it myself and saved on labor cost. There are videos on you tube that will help you. I did order the special socket which you will definitely need to remove n retighten the the threaded end. The other end snaps out and in. You can also rent the socket at your local automotive store. It’s crammed in there but is doable if you know how to use a socket and wrench and wiggle it in to lock in place. Otherwise hire a local mechanic you may know to save a little or pay the high labor price at a shop if that’s your last resort. Good luck and I hope this part lasts for another 170k miles.

Worked like a charm.

Great fit great product
