I just ran across these plugs on another forum, for motorcycles, that I am a member of. Never seen or heard of them before but found them rather interesting. Brisk Silver Racing Spark Plug Online, High Performance Spark Plugs https://www.briskusa.com/ They have some pretty interesting videos that show the different plugs in action so you can see the spark patterns. They have several different styles. Some are designed for boosted applications and there website says that for certain applications a colder plug may be required, which tells me they might actually have a plug that would work properly in "The Beast". Anyway, just thought I would post these up here for you to check out since we had been talking about different plugs.
