I received the parts quickly. The gasket and harness worked awesome, and so did the knock sensors...at first. They lasted about a week and the check engine light came back on. This was a bargain for the intake gaskets and knock sensor harness. But I ended up having to buy ACDelco knock sensors. This job isn't the easiest to do so I don't want to do it over.

Easy install, arrived on time, works great. Came on time. Turned out i had a leak around the intake gaskets on both sides, so its wise to get new ones as they gotta come out anyway

As with every part from 1A, this worked perfect. With the inclusion of how to videos, 1A has replaced the idea of bringing my vehicles to a garage for repairs I can do at home

Did the job 2 weeks ago. So far trouble free. Pretty simple job really. My back sensor looked like hell all rusty and broken where the wire plugs in. Hole was full of water so when you do it , silicone around at least the back hole. The front one looked like new and no sign of water or debris. The kit fit perfectly. Came in a couple days and quite a bit cheaper than buying at the dealer. Job only takes a couple hours if you are a little mechanically inclined.

The parts came right on time! The only reason I gave it 4 stars is because the intake manifold gaskets seemed a little on the cheaper side but the knock sensors cleared my check engine light????

I ordered this after receiving a chrck engine light with a code for one of the sensors. I was a little skeptical after seeing where the sensors were located but ultimately decided to order from 1aauto because of past dealings and the cost was better for the budget. The installation was not that bad and the code went away, have not had any problems since. I would recommend this product and would buy from 1aauto anytime.

Absolutly recommend this product. We have had no luck with the chain stores the Kit we bought was well made- very solid and fit way more snug then others we had bought. We are on our 4th time to replace this and hopefully will be tHe last, because it all fits so much better. Shipping was quick, product arrived as pictured and WAAAAY WAAAY more affordable than the chain stores

Went bad after not even 5 miles of driving. Even checked the sensors with the multimeter and they were reading 99k as they should. Not even 24 hours after install got p0327 trouble code (knock sensor bay 1 low input) the opposite of the sensor that went bad originally. Also the gaskets didn't match my intake for my LM7 5.3l vortec. Would not recommend at all. Spend a little more for the right parts unless you like doing twice the work.
Parts didn't last a day

I bought this kit hoping it would fix my p0332 code for a knock sensor. Upon replacement I found one of the knock sensors covers in water and rusty. I replaced both knock sensors while I was there and I used silicone to seal up the new harness. Everything went great putting it all back together as far as I know of. The CEL was off for a day when it came back on for the codes p0332 and p0327. The new parts not only failed to fix the original problem but also added a new issue with the other knock sensor. I tried to make contact to warranty out some parts but a week later and I still haven't received anything pertaining to my issue. Because of this my work truck has been out of commission until I can get new parts to fix the issue. Not happy with the service if this is a normal wait time for customer satisfaction.
Still working

Possible defective Knock Sensor
Rafael
October 5, 2021
One of the new knock sensors I purchased from 1AAuto may be bad. My 2004 GMC Sierra now has a code p0327 that wasn't there before changing sensors. I had a code of p0332 (Knock sensor 2 Circuit low input) so I changed both knock sensors since I went through the trouble of taking the intake manifold off. Replaced both stock sensors with the new sensors I purchased from 1AAuto. Now code p0327 (Knock sensor 1 Circuit low input). Next step is to test the sensor with a multi meter. Then contact 1AAuto to send me a new one. That means pulling off the intake manifold again. Very disappointed that I may have a defective part form 1AAuto. Created more work.

I Purchased this kit for my Tahoe that had a P0327 code. I installed the kit and with in 2 days got a P0327 & P0332 code. Contacted 1aauto they sent me a replacement knock sensors the replacements lasted about 2 weeks. Do yourself a favor and get acdelco parts not these cheap parts. Contacted 1aauto for a second time and they will not stand behind them. Now I get to spend more money on reliable parts but will be through another company that stands behind there parts. Was a big fan of 1aauto before this experience. Will be my last time shopping with them and third time pulling off my intake.
