Alot of people on the forums here wonder what spark plugs are the best for their rig. Weather it is NGK, Champion, Bosch, or Denso, you want the best for your rig. 99.99% of the time copper core will be the best for the engine.

1: Spark plug mfg.
2: Mileage on spark plugs.
3: Stock or modified intake (NO BRANDS).
4: Year of KK
5: Current weight of rig.
6: City/Highway mpg.
