Exactly what i needed
Perfect fit, can't beat the price. Socket worked like a charm.

So far, no issues with the O2 sensor.

Great replacement
Bought this for my 2002 Beetle that had a code for the O2 sensor. I didn't 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 didn't 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 don't mention.
