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

Spark plugs don't fit nearly as many cars as Revane claims. They definitely do not match Chevrolet products. We left them in our Trailblazer for about an hour and they exploded in the cylinder. These are great products when they have the correct gap but cannot be adjusted according to the instructions. Revain said they would match our 2008 trailblazer but wrong. We decided to try them anyway and the cylinders overheated the spark plugs and they blew up. I had to get a special tool to fish out all the ceramic parts so they wouldn't destroy the motor.
