has any one had better luck with a diffrent sparkplug for the prairie then stock was thinking of looking into maybe a splitfire if they make one for my machine?

 

IMO, it is like running higher octane gas... lots of people do, but with little "real" performance gain... I think you can run a Split Fire plug, but at 2-3 times the cost of a regular plug, you'll likely see no "real" difference in performance on a normal, healthy engine
