    Iridium spark plugs

    here are the 2 types of plugs for the 1300 EFI GPR`s.
    one is iridium BR8EIX, and the other is standard BR8ES-11 NGK

    are these the same heat range? the iridium plug threaded portion is much thicker. Also are these plugs pre-gapped. They measure .028, small for the 1300? what is the correct gap for this plug? Thanks...

    The 8 is the heat range, so yes they are the same.

    Iridium plugs come gapped at what they are. You do not want to try and set it. Ever see what the Iridium tip does to an engine when it breaks off? You don't want to know.

    I put a fresh set of the regular NGK's in each year. If we were to get Iridiums don't they stay in there a lot longer than regular plugs? I have the same denso iridiums in my WRX from 6 years ago and dont plan on taking them out - granted they only have 60,000 miles on them but car runs just as good as the first day they went in.

    Anyone see any performance going with the iridiums?

    So you have to gap the iridium plugs or not?

    I had them and didnt like them compared to my br8es. I felt that I got more life out of the regular plugs. Yes, the they were not as crisp as the iridiums but I felt that if your plug ever got remotely wet or any build up the iridium plugs failed. Just my thoughts.

    I was gapping .026

    No

    If that Iridium tip breaks off, it will chew up your engine like a ham in a meat grinder.

    Never try and gap Iridium plugs
    Never used in forced induction engines. (the tips break off too easily in them)

    If you want a plug that fires easily, use a plain ole copper plug. You want "life", use Platinum or Iridium.
    They will feel "crisp" at first, but will be harder to fire as time goes on.

    My 25cents

    I have never had much luck with the Iridium type plug in a 2cycle. I feel that they oil foul to easy.
