Hey guys I'm just wondering what you guys think my gap (and yes I did do a search) should be on my NGK Iridium spark plugs? I have a Accel coil and a MSD blaster ignition along with MSD wires and rotor.
On the NGK site it said that they should be gapped at .054 for an 88LX. But when I checked the gap on 2(one on each side of the engine)one was at .42 and the other one was at.55. Could that difference make my car run rough? Any help would be greatly appreciated Thanxs!

your gonna have a very hard time gapping those plugs.... if you look at that iridium tip incorrectly, it will break off

Go with autolites

Yeh I know,but I'll have to be real careful. I'm not going to go out and buy Autolites because I paid way to much for these (Yes, I knowI'm stupid)Iridium plugs to just stop using them. So what do you guys suggest gaping them to and do you think the car is going to run rough when the gaps are all different. Thanxs for the help so far!

any ideas guys???

NGKs aren't meant to be re-gapped
There's also a chance they will cause drivabilty problems
(to be fair I've not seen or heard any problems specifically with NGKIris in 5.0s, but do a search for Bosch Plats and 5.0s)
The best advice I can give is to say give them away/sell them to a ricer
If they are not used maybe you can return them (say they were the wrong kind...well, they are)
I'm not trying to be a jerk here, and I'm not kidding
Get some Ford/Autolite plugs
Seriously
these engines and computers like the Ford ignition parts

iridiums are not meant to be re gapped dont even try they will break put em in your car, if your not running nitrous or boost they will run great in there. But it is kind of overkill i got a supercharger and everything and im just running v power ngk's even on kbs website they no longer recomend iridium because you cant regap them and make more power with a copper u groove denso.
