NGK "V Power"

No offense 17, but I hate AC Delco plugs, I've had nothing but trouble with them in my race motors.

I like the ac's,but the 45 heat range is real hot,try a 43ts to start out and if they foul while idling then move up to the 44's,also if you use an electronic ignition add an R to that number for a resistance plug to not interfere with the ignition box.

ac makes a 42 i think they even make a 41(it's been a while since i stopped working at the parts store)try the coldest you get to start with and work your way up. cold plugs will foul and nothing more. hot plugs will DETONATE and we all hate that

When I tune up a gm car or truck I put ac plugs in it .I wouldn't use them in my race motor though.Take a good look at them alot of ac plugs the center electrode isn't in the center of the hole.I use autolite with cut back electrode 0 problems
