Review on Optimized Set of 8 Champion Spark Plug 3013 by Justin Goff

We all know that your spark plug won't work if you drop it. because ceramics can have hairline cracks. Well the package I received looks like it went through hell and back. then the thread on one of the candles was torn off. I had no choice but to install these plugs minus 1 plug (must use the old plug) as I had to use my truck for work that day. (I'm writing this as I've just finished the truck) it works worse than before. I mean where it's not idle. so my suspicion of damaged ceramics was correct. not happy right now as i have to pay the mechanic TWICE!
