Re: Spark Plug Heat Range
were you looking at the plugs after a WOT/clean shut off run? i'm not sure what your looking for in heat in the ground strap but it sound about perfect right now for me. i'd go away from the .050" stuff myself. if you want to pursue the larger gaps your better off to clip the ground strap back & side gap. NGK iridium plugs actually come with the groung strap cut back a tiny bit.
