Re: NGK or Champion?
I don't know about sleds,I think Harley's have there own PLUGS;}Autolites are good! I like BOSH in my truck,I used NGKs in my old 74 Dodge 1/2 Tn van,they where the only plugs that would run in it after 300,000 miles, no lie,318mdl, like a good woman,great bottom end,not much up top,I changed the heads on that dumb thing,???x. I have a Split Fire in my tiller,and in my weed eater,haven't had a problem with them in two Yrs,I don't know if they make a cross over for other things,I think I'll look into that for my Sea King 5. I,m still looking for a sollution for my carb problem.I have a vacuum leak @ the throttle controll housing between the plastic and the aluminum housing,I'm thinking WAX,the extra air coming in up there is messing up my fuel air mix.
