What happens if I run a hotter plug? I was just about to order the NGK BKR7EIX. Which is hotter. I dunno, I don't hurt anything...
Actually both my upper and lower plugs are an 8 heat range.

If you run a hotter plug you have less chance of fouling the plugs but you need to check them after a hard run to make sure they don't look too lean. If you're running on the track, I wouldn't risk it.
