Anybody else tried out the 'Plus' plugs? I ordered a set, but that extra exposed filament makes the plug just a tad longer than the regular turbo plug. Just a slight worry about the piston hitting that. I doubt that it would (can't see GRP getting a patent on a plug that will destroy your motor), and I ran one last weekend with no problem (at least once I got the carb straightened out, which was another issue entirely).
