AC Rapidfires

[MYYellowTY]

Anyone using these or used them before?If so any advice on them.I picked them up havent installed them yet.Wondering if I should go with the ND or AC standard plugs or even the Iridiums instead.Also I know the Rapidfires come pre set and your not suppose to touch it, but should I change it if its over .035 because of the blow out with these engines?And input is great.Thanks All!!!!

Cant belive how much improvement the ingition system makes a difference on these.WOW!! Changed cap,rotor, wires and gona do plugs but what a difference.Plus I think ill take the MSD 6A and coil of my Astro and put it on the TY!! :tup:

Re: AC Rapidfires

What about the Iridiums? Worth it or no??

Re: AC Rapidfires

NGK UR5 are the stock replacements, UR6's are a little colder plug but shouldnt be needed on a stock setup.

If you want Iridiums, then go with NGK Iridium UR5IX, Part # 7177, but for a stock truck, its probably not worth it

I have a set of RapidFires waiting to go in at my next plug change which will be very soon. They came highly recommended even though some on this forum said otherwise so I want to give them a shot.
