    running 15+ psi you could close up the gap a little
    under boost if the gap is too big you can get a miss
    factory gap is for factory boost
    so don't use plugs you cant gap
    I run .035 with the ET and .020 with a turbo
    some tuners keep this fact to themselves

    Many have commented on here that the iridiums are no good for these skis or they have had issues with them. I run the Denso iridiums and have never had any issues with them. Alot of hrs with an ET 70-145.
