Anyone ever use the Ac Delco Rapid Fire Plugs?
I just bought a set of these, they cost almost 4 dollars a piece, I was just wondering if anyone else has used them, and what your opinions where on them. Did you notice any power difference, better mileage etc?
Thanks
Mike

I figured they would be good. I like to stay with the factory brand on certain things (Delco). I am sure they will be better than the stock regular plug by Delco.

Forget the plugs when it comes to power and gas mileage. Get a better ignition system.(ie. MSD,Crane,Jacobs etc.) Plain ol' AC Delcos for $.89 ea. at the parts store are just as good as any over priced plug when the ing. system is good and the plug gap is opened up. The "gimmick" plugs are not worth a hoot. Spend your money where it will count.
$32 for spark plugs...? An MSD Remote coil costs that much. If you haven't put them on yet --get a refund and buy a coil.

Just don't buy Splitfires!!! I got some a year ago, and they run too hot-they're making my car detonate.
