Gapping - Pre-gapped Sparkplug?
Guys,
I have a set of NGK Iridium sparkplugs that I used for about 25 miles. They were installed when my supercharger was installed but because I was running so rich they fouled out pretty fast. Well, I cleaned the crap out of them last night and they are good to go. Except for one problem
7 of the 8 look fine - but the last one is not gapped properly. The electrode and the other thing are basically touching whereas the other ones all have the same gap.
Can you gap a plug like this that is pre-gapped? I can't find anyone locally that has one and I am ready to get the car back on the road. Please let me know asap as I want to put them in tonight.

Maybe I'm not understanding correctly, but why can't you just regap them? I check all my pre-gapped plugs before installing anyway. I think it's always good to check anyway, and not just blindly install the plugs. But that's just me. Get one of those $0.99 gap tools.

What's more important is that the one plug has "no" gap, indicating that it was struck by something. Not knowing how serious the damage is to the plug, I would sugesst replacing it, if not pick up a spark plug gapping tool from Autozone or Pepboys that has the ground electrode bending tool and gap it to match the others. If it still runs rich, you have a bigger problem than just spark plugs.

I just had a issue with the iridium plugs I put in the wifes car last week. I used that .99 cent tool and the iridium electrode got pushed into the plug (not good).....so make sure if you use that tool, use the part in the middle where there is a little hole and bend the arm. This way you dont touch the electrode. Hope that makes sense.......
Bend just slightly then put the plug on the edge to see the gap you have.
