    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.

    Rated 5 out of 5 by from NGK V POWER FR5 SPARK PLUG I recently purchased a set of Trick Flow heads for a 355 (.030 over) small block corvette. I plan on purchasing a set of Side Mount headers. The Trick Flow heads call for the FR5 plug. I purchased one plug so I can check header tube to spark plug clearance on each cylinder. If there are no interference problems, I'll purchase the other 7.
