Ok, nice video!

Fancy plugs just don't seem worth it to me. I'll still replace them at the recommended service interval anyway.

i would double check those numbers

Makes sense! ...then, while you're at it, may as well add another relay that inhibits the headlight while the starter motor is cranking, so more power could be devoted to cranking / igniting.
