    Any gains from Iridium plugs?

    Are there any gains to be had from running the Iridium plugs? I have heard you don't have to J-gap them, so are they a bolt-on rpm gain?? Anyone have any before and after rpm numbers?

    I tested them against the stock plugs a long time ago and got no rpm gain. They did tend to run a little "cleaner".

    I have seen that they are safer when running lean .(they didn't melt as fast)

    newer findings is that you must run them at a higher gap to see improvements other than smoother running (warning:bend the ground electrode back,do not not force the gap wider with a gapping wedge tool) ..see my recent thread link posting in old school for further thoughts ..
