DO NOT BUY, I repeat DO NOT BUY... save your money and go somewhere else. Their product is crap and they won’t refund you. The knock sensor and harness were installed in my vehicle due to knock sensor code. After installed the code came back. We replaced other parts that might be triggering the code because we didn’t realize we were sent a crap part. Finally we ordered a factory knock sensor and harness kit and the code is gone. Tried to contact this company and I get an email stating no refund. I’m out the $60 plus the other parts that did not need to be replaced because of this company’s crappy parts. DO NOT WASTE YOUR TIME WITH THIS PRODUCT OR COMPANY

2006 Avalanche replacement. Fits perfect, no more knock sensor code. Includes wiring harness. You will need to buy intake gaskets and RTV or similar for water dam in front of new knock sensors. Leave rear open so water can run of the back of the valley pan due to natural front to back decline of engine.

I've viewed A1Auto's help videos for years, decided to purchase these knock sensors from them. My '03 1500 Suburban was consistently getting a P0332 code and occasionally a P0327 code and SEL too. After careful consideration I went with this kit which is about 1/2 the price of OEM, even though I heard some questions about the quality in general of aftermarket knock sensors. When the order arrived it was missing a knock sensor. A1Auto was great about sending the missing sensor and I had it the next day. Unfortunately after replacing the parts I started getting a consistent P0327 code and SEL. Long story short I ended up getting the OEM parts local (quadruple the price!!!) because I need to get the repair done. The OEM parts fixed the problem and now no codes or SEL and the suburban runs better. A1Auto issued a full refund, no return required. I'll definitely do business with and buy from A1Auto in the future but if you have an older, high mileage chevy 5.3 motor like I do, stick with the OEM knock sensors and harness, for whatever reason these just don't work in these situations. Further research on the internet and now my own experience confirms this. The other good news is I can now get the intake manifold off my suburban in less than an hour ;)

It didn't take long to get it and it was a complete set.

Excellent value for great parts. The harness was an improvement over the OEM design and should help keep water out of the stupidly designed holes on top of my Chevy motor where these sensors are installed.

Purchased these sensors based off of the reviews. My 2004 Chevrolet Avalanche recently failed smog check due to one of the knock sensors being low voltage and check engine light. Auto parts stores wanted $43-$60 each and $22 for the harness. Luckily I found this bundle deal. I was a little concerned. Read how after market sensors are flimsy. But not these sensors. My mechanic approved and installed them. It's been 4 days now, engine light is off and it seem to restore some power. I will update if it passes smog test. Thank you for all reviewers reminding not to forget intake and throttle gaskets.
