What kind of spark plugs does everyone reccomed? I got MSD wires, but i don't know what kind of plugs are good. Also, is it worth spending more money to get platinum ones?

(annealed) copper plugs conduct very well, but they suffer gap erosion sooner (than plats). plats receive mixed reviews from 5.0 EFI guys - some have experienced low idle and high rpm cut out with plats. i use plats on DD's i dont care about, or cars that are impossible to do plugs on (i.e. 4th gen camaros).
iridium conducts well and lasts long (very hard), but they are $$. i would not run them unless severely blown or nitroused and other plugs are being snuffed out.
back to my tire analogy: do you want to drive on nice sticky kicks that hold like rails, but dont last long. or do you want some really hard crappy tires that last forever, but dont hold the road at all? the former for me.
for my fox, i run autolites (25's) - no complaints. a lot of the fox guys like those or motorcrafts. i will add that some have been liking NGK's - ive run them on my bikes before and they were fine. i dont know the guys who recommended them - so i dont know how they 'really' compare. just something to think about. i doubt you can go wrong with any of these.
alum heads will take different plugs also.
my two cents worth.

how much do the iridium plugs go for? (i.e. the denso iridium plugs) i saw the denso tent at the NMRA nationals and their brochure claimed horsepower gains by switching to their plugs on supercharged applications (their brochure claimed 23 HP on a supercharged '01 bullitt)...i doubt a n/a combo would get anything close to that, but i wouldn't mind gaining a few HP from just plugs...any thoughts?
