NGK #5019 G-Power Spark Plugs LTR5GP - Brand New Set of 6 Pieces for Optimal Ignition Review

The spark plugs were great for the price and easy to install but we encountered a problem after installing so we took them back to find one was cracked.

Good product but DO NOT try to split them, they come with the kit and if you try to split them unscrew the ignition tip and it will fire Not. Chevrolet Trailblazer 2004

Received a week ago. Installed yesterday. They went in easily and looked exactly like the ones I pulled out (except they were a different brand). The messenger caught fire and ran smoothly. I also replaced 5 ignition coils as I had them and an engine code indicating a misfire on cylinder 6. Haven't tested it on the road yet but I think they will work fine.

I didn't know any better, I'm glad I checked and ordered because my machine's performance has improved a lot since then and it's running smoothly. I think you've already noticed how little I know about cars. All I know is that they worked for my car and improved it.
