The part came in the original Denso box with a tube of thread anti-lock cream. My 2000 Subaru Impreza's check engine light came on and the OBD-II error code was a P1133, replace the air fuel mixture front oxygen sensor, Denso Part 234-9018. Originally, Amazon claimed that the Denso 234-9018 was the wrong part. But I checked other vendors and this was the correct part.I had a bear of a time disconnecting the oxygen sensor from the wiring harness since the drive shaft is in the way coming from underneath the car. Unscrewing the old oxygen sensor was easy with a 22mm box wrench. The whole job took less than a 1/2 hour. Started the car a couple of times and the check engine light turned off.I made the mistake of ordering this part with a book I wanted - BIG MISTAKE! Amazon waited to assemble the package 10 days before I got the part. Needless to say, I would have gotten the part in 3-4 days if I had ordered the part by itself. If you need an oxygen sensor, Amazon has the best price for this OEM part.
