NGK patented V-grooved spark plugs are a technically simple but very effective spark plug solution. A V-groove is situated in the centre electrode of these V-Line spark plugs. This forces the spark to occur at the outer edge of the centre electrode where it is easier to ignite the fuel/air mixture. In addition, the voltage required to produce a spark is reduced. These two features give the benefit of improved ignitability.
NGK V-line spark plugs offer perfect ignition of the fuel/air mixture. Especially in modern low emission lean-burn engines, even under extreme operating conditions.
