Never use the Bosch plugs. If they ever for some reason or another foul out they will not clean themselves out. We had a shop and had more than a few cars coming on the hook just because of this brand of plug. use NGK or the original AC plugs that were designed for your car.
Has anyone used Denson T16 or T20 plugs? I was told to try them in my LT4. I did hear the TR55 is also good. Any help ?
