There's a "hot" (for 'city'-usage) and a "cold' (highway-usage) spark plug range, for Champions (& other brands). My D500 runs like a Champ, on/with Champions , but with its elect. ign, it's been awhile since I've 'thought' about the 'plugs' (I think their the 'cold' type.) BTW, if you haven't replaced your air cleaner recently, you'll be impressed @ how well it performs, if/when it can breath!
