I would only use AC Delco sensors......but I had no choice but to go with Densos a couple weeks ago when one of mine took a ****. Perfect so far.
ALSO, a couple weeks ago when I ordered brand new AC Delcos from Bennett Auto Supply, when I got there and the guy handed me the AC Delco boxes I opened them up and what did I see inside....Densos. So I asked him to go in the back and get me two Densos sensors, I took them out and they were 100% identical down to the bags they were in, instruction paper and anti-sieze tube inside the bag. I said, "whats up with this?" He had no idea. But the AC Delcos were like $25.00 more for each sensor.
So obviously I took the Densos.
So either someone stole the AC Delcos out of the boxes and replaced them with Densos...or GM is now contracting with Denso for their 02 sensors.
Either way, they are working picture perfect. I paid $120.00 for both, with the 15% discount coupon Bennett has on their website.

I currently use Bosch sensors but only one is regular narrowband O2. The other Bosch is a wideband that goes to a controller that emulates the narrowband signal and feeds that to the PCM. Seems to work ok.

I wouldn't be surprised if they're both made by the same company....kinda like oil pumps...from what I read there's only like a few major manufacturers that make them (stock design anyway) then everybody else reboxes them..you can tell by the markings on the body..same with everything, tools, dealer parts, store parts....Just like Autolite makes the Motorcraft plugs for Ford and Purolator makes the oil filters for Motorcraft I believe.....I've gotten plenty of dealer parts that said "made in Taiwan, China, etc" or built by XXXXX to OEM's specs and thrown in a "genuine dealer part box" and with a Stealership price tag.
Maybe in GM's tough times right now they are using Densos. They're less than half the price of the AC Delcos for each sensor. The retail price at the dealership is $190.00, my friend who works the parts counter gave me a discounted price of $130.00 each. I got my Densos at Bennett, BOTH for $120.00.

That is good to hear![Thumb](https://ls1tech.com/forums/images/smilies2/thumb.gif)
The vette o2's are longer so you use them instead of extensions when installing longtubes. It didnt make sense to me to buy extensions for my 100k mile o2's, then if one of them burnt out Id have to spend more money to replace a stock short o2. So instead I replaced both with the new vette o2's with a one year warranty. Paid off too because a month later my longtubes burnt out the first set, warranty replaced them, been good ever since...

Soon after my header install I burnt up both my stock sensors. I replaced both with bosch 13111s and it is already throwing an o2 sensor code. They've only been in there for about 5k miles.
