Review on High-Performance NGK #5019 G-Power Spark Plugs -- LTR5GP -- Set of 4, Brand New by Randy Albright

Installed July 2018, now December 1st. Two plugs are missing tips. They have gone to the great afterlife. These plugs are absolute junk. STAY AWAY. Disappointed, breach of contract. These forks arrived in minimal packaging which was good but not enough protection as the tips could get damaged. They weren't damaged, so that's good. The package had individual boxes, not a box that had individual boxes. This allowed them to move around a bit freely during transport. The worst thing is that they don't contain BREAKING WASHERS. They are important in preventing the piston from being pulled through metal to metal in the head, act as a seal and provide depth control by acting as an adjuster. They work great and are fully functional. Smooth work. No misfires or MIL messages. Vehicle: Chevy Cobalt LT 20062.2 EcoTec DOHC
