[QUOTE="jackson409, post: 32785, member: 381"] That plug is not your problem. The reason for the high dollar plug is because of the electrode, not a fouling issue. On a standard plug, the electrode had a bad tendency of breaking off due to the vibration of the motor. You know how those zooks make HP:smirk:. The broken electrode would then beat the top end to death. That rarely happens, but it happened enough that Suzuki decided the high dollar plug with the solid one piece electrode was the fix.
