they look good. Don't change a thing. if anything your running a touch lean, but if it's EFI your good. I had to change mine to a colder plug. my stock ones were running hot.. they showed it. I always reccomend 1 colder than stock if you have any modifications. In my TPI L98 Corvette i went like 2 or 3 colder. car ran so much better. I had 50% less spark knocks on the scanner. If you look at today's performance engines like the LS1 and LS6 they run plugs much colder than the 80's. B/c of emission control systems of today allow us too. So if you have an older engine.. go colder in most situations. B/c they ran hotter plugs to burn up as much as possible in aiding reducing emissions. "I HATE THE 80's!" who's with me on that? Era of 100HP Z28's. Horrible time for cars.
