hey, picked up a split fire spark plug today the only problem is that it is 1-2 heat ranges hotter than stock (the split fire catalog even list it for 1-2 heat ranges does't go in 1 incements). so my question is should i try it or am i asking for trouble? just worried about piston temp , please let me know what you think... ngk part# is dcpr8e which crossed to the split fire part # sf416d thanx matt
