Platinum plugs - gap or pre-gapped?
Hi guys,
Just picked up 6 NGK Laser Platinum plugs for the Max, and 5 of the 6 boxes say "Do not adjust spark plug gap due to possible damage to the center electrode", and one says "Gap plug to engine specs".
SHOULD these plugs be pre-gapped? I know that two of them were way off the .044 called for - one was about .035.
Need to know so I can either take these back or gap them so I can get rid of my spark knock this weekend!
Thanks,
Jack

Regardless of whether or not the package says the plugs are pregapped or not you always check them, as you have all ready done, and then gap them to the proper specification for your car. I would not worry about damaging the electrode unless you feel you're a bit clumsy.

I always check and adjust the gap as needed. If your really worried about it, go to NGK's homepage and send them a question. I just did that the other day and they actually answered back within 24 hours.

If you're doing it right, you never touch the electrode while you're setting the gap anyway. Only bend the arm. Don't ever lever against the electrode. I never install a plug without checking its gap.

Here's what NGK said:
Here's NGK's reply:
"For these plugs they should already be factory set to 1.1mm (.044") and
will not require adjustment prior to installing. I would suspect you are
probably usin a coin style gapping tool which is not very accurate when
checking the gap on fine wire plugs. My recommendation would be to
install the plugs as is and just be sure they are all at the same gap
prior to installation. Hope this helps, thank you."
He was right, I was using the coin style to check. I'll spring for a wire gauge now, I suppose.

Also, FWIW, "racing" plugs (I'm interpreting that as "iridium plugs" are a waste of money unless you're truly racing, using high boost or nitrous, which significantly increases the heat in the cylinder. For pretty much all other occasions, good old NGK platinum plugs off the shelf from the parts store are your best bet. (<~~~ my opinion, of course...all usual disclaimers...)
