working well for the past 30,000 miles
Thankfully, the code came back right away and I double checked part numbers at another site.
In any case - installed easily (albeit in the wrong location) with some extra leverage from a cheater bar. Also don't forget to remove the wire before wrenching it and to be aware of any locks on the wire connection you have to push down before pulling (it may help to have an extra person to hold the release). Knocked it down a star b/c had a hard time fitting the shrink wrap over the butt connectors and it was barely long enough to seal both ends; I'll ditto the other reviewer that advised to run out to radio shack to pick up the yellow 22GA butt connectors and get some longer shrink tubes.
Overnighted the correct sensor now (Denso 234-9050) and hopefully the connectors are the same **knock on wood** since I might as well use this one to replace the old downstream sensor.
Will update if any issues occur once sensor is installed correctly.

overall im thoroughly impressed with my purchase, it came faster than i needed it. and for the price i am still asking myself why anyone would pay 2-3 times more to save themselves 10 minutes of crimping.. unless of course you are some kind of multi millionaire...
