need help quick with plug gap

[vic ray]

hey guys,

I am in the middle of a plug swap and need to know what the suggested gap for the ngk iridium plug is. I have the manual but I just was thinking the gap for the regular plugs might be different. I am doing this now so a quick response would be greatly appreciated.

.028...............same as stock To double check go to a NGK site

Thanks for the quick reply I appreciate it.

I recall something about not screwing around with the gap on the iridiums, as it is a small fragile point. I installed them out of the box, for better or worse, based on this internet enhanced knowledge. :blink:

FWIW, I checked my old iridiums that I had pulled with 20K-miles of service. The gap on the used plugs was .030 across the board--within the range recommended by the stock plug (.028 to .031).

DO NOT RE GAP THE IRIDIUMS!!!!!!!!!!!!!!!!!!!!!!!. I already started a thread long ago when I did the same thing. The gap is already pre-measured at the factory. Any attempt to adjust or check will damage that stupid electroid. Believe me, I did the same thing, ran terrible, and found out a little pressure will crack the stem. NKG told me they couldn't replace or exchanged my plugs because I didn't read the warning sheet. There is supposed to be a warning insert about damaging the plugs to check the gap. Yeah..I found it after the damage was done. From the packaging, just install the plugs as is.

Yup. Leave 'em alone. Unless the package was dropped and the ground closed up, which would be obvious, they are pre-gapped and ready to go.

.028 - .031 is the tollerance. I checked the gap on mine last weekend and they were all within that range. One was a little tighter than the others but only by a thousanth or two.

But that brings up a question. What about using a gapping tool that only moves the bendy bit and not the pointy bit?

{[google search] ground electrode and center electrode}

So a tool that adjusts the ground electrode at its base without getting near the center electrode?

One of those would work, but don't be "Ham-Handed" checking it, I have seen some who would bend the electrode trying to force the gauge in.

Hasn't every spark plug in the last 20 years said not to re-adjust the gap?
