  • Modern, lean-burning, fuel-efficient engines call for new lower sparking voltage requirements. NGK Spark Plugs responded by developing V-Power Spark Plugs with V-groove center electrodes. The V-groove center electrode forces the spark to the ground electrode's outer edge, placing the spark closer to the air/fuel mixture to ignite it quicker for more complete combustion (thus greater power & less harmful emissions).

    Today's performance engines are often high-compression/high-stress: supercharged, turbocharged, or fed by nitrous oxide. Ideal for high-performance street and race cars, NGK's patented V-groove design allows an ignition system to spark easily in such dense air/fuel mixtures. The flame kernel grows rapidly and enables an engine to potentially make more power because it's operating more efficiently. As a bonus, the spark's outer edge location helps limit the quenching effect, reducing misfires caused by high cylinder pressures "blowing out" the spark. V-Power Spark Plugs also use lower ignition firing voltage, which results in faster starts and easier cold starts throughout the life of the plugs. Sold individually.
