Came gapped properly, good plugs that work well in my high compression big block Mopar. Nice cold plugs for the occasional use of nitrous as well.

Dis product is not a good quality. It lasted 2 month and with it went my egnition coil. Wanted to save 150 bucks, but ended up getting new spark plugs and coil. 400 bucks out of pocket. Doesn't worth the headeck. Buy from your local store. Don't try to save money on thw plugs it can take down the entire engine.

One from for was not working properly! Now seems that a second one is doing the same thing.

Caused me more problems. It might work for other cars but it doesn't work for chevy Trax. Think twice if you are buying for Trax even though amazon says it's compatible.
