AC Delco Replacment was exact.
Took care of Bank1 sensor 2 Code on my 2016 3500 Duramax. Check engine light and service fuel exhaust now 99miles to 65mph .Exact fit and shipped fast. Took 20 minutes to remove and replace. Best to cut wire off old one and use a socket. Error cleared with new sensor.

Cheap alternative
Bought for a spare back up sensor for my 2015 Arctic cat XF Highcountry 8000 I haven't used it yet but it looks like it will be plug and play. Stock sensor was way over priced and read that this will work just fine.

Great replacement part for other applications
Used a replacement for egt on a 2006 Ski Doo Summit REV 600 SDI - ski doo's cost is around $200 so this part was a bargain. I had to cut this end off and solder on the ski doo end, but otherwise this part works perfectly for a fraction of the cost

I went to get a fuel temp sensor for my 2014 arctic cat zr8000 snowmobile. The Cat dealer told me to purchase this sensor instead as it is identical. The sensor from Arctic cat was 180$, versus this one. It plugged right in, improved my fuel economy and removed the engine light off of my dash. Great product.

I used this on my 2007 Ski Doo Mach Z 1000 it is the exact same one used by Ski Doo only 1/3 the price. Just used my original plug and solved my check engine light.
