spark plugs

[Diablo3305]

I've been looking lately into getting new spark plugs. Im looking at either the denso iridium's, or the bosch +4's...anyone have any opinions on either of these, or know any better ones that are out there?

Save your money and get a set of factory recomended Motorcraft plugs. The engine was designed to run with these plugs, and unless you have done any serious modifications to your engine, anything more will be a waste of money. Use the money you save on the plugs and put it towards a set of good wires.

I just put in the +4's in my S10 and I can't tell the diff in the regular Bosch platinums that they replaced. I'd stick with the regular platinums.
