what spark plugs should i use in a 96 ultra sp?i bought it with br8es and it and i think it should have 9's.should i just go with the hood stickers and run the champions?

I think my book says the 8's in there...On the inside of the hood it will say too, u cant go wrong with following what it says there either...

Either way Champs, or NGK's both good plugs. IMO

Champion RN2C's or NGK BR9ES is nearest crossover.
The 8's are hotter and alot of people will put them in to solve fouling problems instead of fixing the corroect way.

alot of money for nothing! i tried running expensive plugs and regular ngk's. and did not see a improvement, if you are racing and need everything running optimum performance then their worth it.
