    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.

    JEGS Easy Kits are designed by JEGS Professionals to help you get all the performance parts you need.
