    I'm a fan of NGK Iridium. Heat range: I use the 7's. Lower number has more thermal isolation from head and runs hotter. Autostrada, autobahn or track ---> 8 , Slow running, or maybe a bit of oil present, ----> 6 or 5. As far as gap: the MSD puts out a strong spark, and can jump what ever gap you challenge it with. Larger gap means higher spark voltage which is harder on ignition components. I've been at .028" w good results. Curious what others suggest.

    I have ngk iridium
    8s on the shelf so will put those in. I remember years ago 8 fouled up at ties so went to 7s.

    slow running or a bit
    Of oil present I guess 7s. Mostky not slow running, but backroads so only 3rd and 4th 3500-6500 rpm.

    I use NGK BP7ES in my BBi. I haven't had any issues, but I've also not experimented much to see if there's a better choice.

    8s are too cold for a Boxer.

    Got some BPR7Es.
    Just finishing up the neatening and hiding of the wiring from the MSD. Will do the plugs and see how it all runs tomorrow am.
