if you want to give iridium plugs a try, don't pay $12 a pop for them. you can get NGK Iridiums at Napa for $8.25 each, and i could install them for you. it would only take 20 mins at the most. you could get them for even less if you order them online. FCP has them for $6.80, but it says they are for non-turbo cars. they are the same part number that i bought at Napa though.
just remember you have to buy 5 of them.also, unless you are having misfires when you floor it, i wouldn't worry about re-gapping them.
