Knock sensor kit
looked for a kit in town but couldn’t find the complete package. I was able to find what we needed for our customer and save him money! Part came by overnight shipping and we are well pleased with the quality of this product! Thanks 1A auto
August 14, 2018
Kit worked great!
Everything was included in this kit to complete the job!

September 6, 2018
Parts were shipped promptly and were correct.
I appreciated the verification of fit to my vehicle prior to placing the order. Parts were correct and promptly shipped to me.
September 7, 2018
cheap parts
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 isnt the easiest to do so I dont want to do it over.
September 13, 2018
I really enjoyed how fast and safe everything got here. I recommend this product for anyone who is in need because it’s totally worth it
September 14, 2018
I have purchased many items from A1 Auto always on time always fits excellent customer service highly recommended

Great!!
This is a great product. Fast shipping, easily interchangeable with the old parts.
September 20, 2018

Knock sensor angle harness kit
One of the sensors Is Malfunctioning already. I have to cool the intake back off M replace bank two. Didnt last two weeks
October 29, 2018
Great products and great customer service!
As I searched the internet looking for a knock sensor for one of our cars I came across 1A Auto. They have fantastic customer service and fantastic please. Ive already ordered from them and will continue to order in the future. Thank you, Natalie M., Powerhouse Auto, LLC Smithfield, North Carolina
November 11, 2018
Knock sensors
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
November 13, 2018
The right fit
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
November 30, 2018
Very satisfied customer
I will defiantly buy from you guys again. Great parts at awesome prices and really fast shipping! Thank You!!!
December 3, 2018

Exactly what I ordered
Ordered a knock sensory kit for my truck, very reasonably priced, perfect fit. Works great. Problem solved.
December 9, 2018
Good fit
Came very well packaged and correct parts. Plan on using 1aauto again when I need repair parts
December 10, 2018
Good Choice
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.
December 20, 2018
A-1 is the Tops
Parts ordered were correct, great prices, fast delivery and pleasant personnel.
December 24, 2018
Excellent service
Excellent service, shipped quickly and exactly like it was supposed to be. Will definitely use again.
February 7, 2019
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????
February 13, 2019

2006 silverado knock sensors and gasket set
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.
June 11, 2019
1A Great service
They had exactly what I needed at the right price. After ordering I received my parts exactly on time and was very satisfied with 1As quality and service.

Knock Sensor Kit for Chevy
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�

2005 Chevrolet Silverado parts
All the sensors and gaskets I ordered for my 2005 Chevrolet Silverado were amazing. All fit perfectly and resolved all my issues. I would strongly recommend 1A Auto to anyone wanting to save money and get great products!
March 2, 2020
Low quality

March 10, 2020
Quality
Worked and sealed great have had no problems
March 29, 2020
Just right
Great job y’all !!! Everything fit just right and works perfect !!! Thanks !!!
April 6, 2020
Junk, buy AC Delco
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 didnt 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.
April 18, 2020
Parts didnt 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 havent 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.
June 20, 2020
Still working
Put these in last year. Cleared the engine code and has not returned
August 18, 2020
Very happy with the product and price!
Cant go wrong for the price! Will buy do business again! Alot better then over paying at the auto parts store!
August 20, 2020
Amazing
Everyone says go OEM or they will go out within a week on theese parts. Well my check engine light is off and my silverado has been running great for about 6 months now with no issues.
