Improve your engine’s combustion efficiency by replacing your plugs with SplitFire spark plugs. Unlike typical plugs, they have a “V” design on the side electrode that allows unrestricted flame travel from their copper-cored center electrode into your combustion chamber. They have a precision-tooled metal shell to resist seizing in your cylinder head. Their smooth ceramic insulator eliminates spark flashover that can lead to ignition misfiring and potential damage to your engine.
