Great replacement
Bought this for my 2002 Beetle that had a code for the O2 sensor. I didnt know that this O2 sensor was different between engine sizes and had bought one from another retailer that turned out to be wrong (too long of a cable and didnt have the same mating connection). Returned that one and bought this one instead. It fits perfect and immediately cleared the code. No issues since install. Because of this, I now go to 1AAuto for most of my needs first, especially on parts like this where there are minor differences due to engine sizes hat other retailers dont mention.

Bad Part
I am very disappointed in my order as I received a bad part. Installed it in the car and immediately the cars engine light came on and said it needs to be replaced. Went to a local parts store while the car was still on jacks got the part I needed and it worked perfectly. Engine light off and passed smog. They will not refund my money even though the part was crap!!
