Item was just as described and a prompt delivery. However, it didnt fix my problem even though my old 1 was broken in half from the last installer crankin the nut on it. But that has nothing to do with the product. Thats my car it took 10 parts and $100's to fix. Fine product and using the free coaster now thank you.

I needed to pass inspection and my old knock sensor was giving me a check engine light. So i found this knock sensor for cheap. I was worried, but i didn't want to spend the crazy 80+ from an Auto Store for such a small piece. I installed this and it worked!!!

Great item and 30 minute install if your mechanically inclined, noticed a difference in car perfomance! Cant beat this price!

Fixed the problem for a tenth the price "discount" auto stores wanted for it. I think I lost the coaster though.

Looks like the original part. Have not put it on yet, but I'm sure it will work.

This knock sensor may be cheap but it's a very good product, it did it's job, my mechanic didn't believe the price I paid

I really like this product. my car's knock sensor was shattered so I found this one for a really good price. It has not let me down. I would highly recommend it. The coaster was a nice gift too!

Works great got rid of check engine code for it
