The kit came in 2 packages, one package with the harness and the gasket, the other package had the sensors. One of the sensors came in defective. Had to pay the shop to do the labor twice.......not good

This was the perfect kit to fix my knock sensor issue and I opted to replace both sensors and the harness because I only want to do that job once. Everything so far so good

Bought my knock sensor from A1 for half the half price at any store and can't be any happier with them working great. Delivery was on time like the estimated. Just ordered more parts from them.

I received my package on time as usual. The only problem is the cheap gaskets sent with it , they make a steel version that is superior to the factory ones .
Worked great

If you are getting the code p0332, itll be the engine knock sensor in the back, I got the kit because it is cheaper and over all easier. Thanks to 1aauto, I was able to get my truck running again and do the work myself with their super helpful videos

I compared this kit to others offered by other vendors. The ratings, price including shipping led me to purchase this kit from 1A. Delivery was quick, the items were well packed and everything fit exactly as they should. My Suburban runs better than it used to and I will be buying more stuff rom 1A in the future.

The gaskets did not clip on right and one of the knock sensors twisted of in my block with barely any force once I began to tighten
Service was excellent

Engine knock sensor and harness

I purchased a engine knock sensor and harness. The knock sensors and harness kit was packaged well. The video on the website told me step by step how to fix the problem for my Chevy avalanche. The fix went well and all of the things I ordered fit and worked. The next day while driving to work my check engine light went off and the truck has been driving normally since. I was happy the knock sensor kit was affordable and good quality.
Would recommend for 99 5.3

Worked perfect for 99 5.3 Silverado. I would recommend this kit. Take your time and clean the intake and head surfaces.
