? about spark plug gap

[Jinx]

OK, it's time for me to replace my plugs. I have the motorcraft platinum plugs with the longer threads. They are pre-gapped at .054.

My question is:
With a Predator HP tune, advanced timing and premium fuel, should I alter the gap to be smaller or larger by any amount, or should I just check to make sure they are at .054 and plug-n-play?

anywhere from .050 to .054 will be fine if you are NA

no reason to change the gap yet keep it

Unless your going blower, turbo, or nitrous I would keep the stock plug gap.

I was mainly curious, because I have read in here that some people will go with a slightly tighter gap on the copper plugs (due to the fact that they wear faster and a slightly tighter gap will help lengthen the time before a removal and re-gap is needed), and was wondering if this was applicable to the platinums.

Nah. I use copper and .055. It's good right there.
Always check the gap when you buy new plugs before the install.

I would recomend going with the motorcraft sp-505 plugs because they are at a lower heat range than the sp-493 which are the same as the stock one, keep your gap at .054

Always

Well got the plugs, now just have to find the time to do it (no garage .)
