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

VALUE is more for LESS. IMPORTANT - ALWAYS BLOW OUT THE SPARK PLUGS BEFORE INSTALLING SPARK PLUGS. They say they are "Pre-Gapped" but that is NOT TRUE. ALWAYS use a spark plug gap gauge to check the gap before installation.

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…
