Anyone try the E3, iridium, or Bosch Platinum+4 plugs? Which is better if any?

It probably won't make a difference unless you start boosting or using nitrous. I could be wrong though.

i've always heard that the irdium were the best, seems to be the best, others that have the extra prongs are really more for looks than any thing else, sure they last longer but there is no more power delievered from them, remember that eletricity can only "jump" to one diode at a time unlike the commercials that you see with the spark jumping to all three or four prongs at once

I think their point is not that there are 4 places for it to jump, but for them to have the spark unblocked directly pointing at the piston. Triditional spark plugs have a piece of metal blocking the spark to the pistion, where as the +2 and +4 plugs put the spark directly above the piston. With a triditional spark plug the spark is to the side and it must fire to the side and ignight around a cerv to get to the piston. It is like pointing a flash light in the dark at what you want to see, then putting your hand a few inches in front of the beam. Yes the light gets there, but it is being hendered by your hand. The +2 and +4 are open to the piston, like removing your hand from in front of the flash light.
