Oh, I know that for sure, I'm not going to run out and throw some Bosch Platinum +4s or anything in
But alot of people have a brand preference, and for a good 'ol American V8 I thought I might get some people chiming in with plug XXX thats hotter or colder is better because the factory plugs were best for emissions, blah blah... stuff like that.
Same goes for gap. I know people pick different plugs and gaps than the factory recomended, but I don't know what or why
Try asking "what spark plug should I use" in a Motorcycle or Jet Ski forum and you'll end up starting a raging debate
