Original GM replacement knock sensor
It's working great so far. Got rid of the check engine light and the related multi cylinder misfire. However, I was sceptical if it really was a genuine GM part, because it had a label instead of being engraved like the original part.

Nice original sensors, walmart beat the auto parts store by almost 1/2 for same part, ohmed out at 100k which is perfect, and in GM packaging

Exact fit/great price.
Exact fit. Also, much cheaper than the dealership. Lastly, the pickup at walmart was excellent. The pickup rep had my item to me in less than a minute.

OEM Part
This is the original manufacturer part by ac delco. The price was excellent. 2 for the price of 1 from Walmart. You certainly can't go wrong.

A/C delco knock sensors and dorman harness.
After researching the P0332 problem I found it was best to purchase oem sensors. I don't want to replace these again. Someone on a forum mentioned wal mart had the best price and they were right. I ordered them and payed with paypal it couldn't be easier.

Great price
These knock sensors were $20 less then anywhere else I could find. The only negative I had is I paid extra for shipping and they were late. I contacted Wal Mart customer service in chat and the refunded shipping for me. Was still disappointed they were late but I was still happy with the service.

Failed after two weeks - can't return
It took me 2 hours to install knock sensors in my 2005 Chevy Suburban. In preparation, I read a lot of blogs and watched a lot of videos. ALL of them recommended buying AC Delco sensors (original OEM). Well, I did and well... they failed. And I can't initiate a return because the return window is so short. I recommend you buy local, even though you'll pay more, so you can make sure the supplier stands by their product.
