dont they achieve the same basic results?
shortening the gap decreases burn time
cooler plugs allow for a decreased chance of pre-detonation
these both have a direct relationship on burning efficiency would they not?
you have your plugs gapped at .35 stock for a 99-04 i believe is .55 (i cant really remember) if you wanted to increase the gap enough to make a difference you would most likely have to run a cooler plug right?
my original point to the OP was that he should have done one of these to begin with
