Modern lean-burning, fuel efficient engines create a new set of requirements for spark plugs. NGK Spark Plugs answered the call for a spark plug with lower sparking voltage requirements by developing the V-Power, the only spark plug with a v-groove center electrode on the market today. Why is this important? The v-groove center electrode on a V-Power spark plug forces the spark to the outer edge of the ground electrode, placing it closer to the air/fuel mixture. What this does is allow the spark to more quickly ignite the mixture, providing more complete combustion.

More complete combustion not only provides more power, it also means less harmful emissions. These emissions are not only damaging to the environment, they can reduce the life of expensive catalytic converters and oxygen sensors. V-Power Spark Plugs also require lower ignition firing voltage, resulting in quicker starts and easier cold weather starts throughout the life of the plugs.

NGK's patented v-groove design allows the ignition system to easily spark in these dense air/fuel mixtures. The flame kernel will quickly grow and allow the engine to potentially make more power since it now is operating more efficiently.

As an added bonus, the v-groove forcing the spark to the outer edge of the ground electrode helps reduce the "quenching" effect, reducing misfires caused by high cylinder pressures "blowing out" the spark.

They are available in 1 step colder than stock and 2 step colder racing plugs. Select your option with the drop down. It is not recommended to run 2 steps colder except in race or nitrous applications as they foul out quickly.
