NGK V-Power Spark Plugs
Advanced V-groove center electrode provides optimum performance and fuel efficiency required by today's lean-burning engines.
V-Groove Design Enhances Ignitability
More Complete Combustion and Lower Emissions
Racer's Choice for Performance
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 V-Power Spark Plugs also are ideally suited for race cars and high performance street cars. Today's performance engines are high compression/high stress applications. Many are supercharged, turbo-charged or nitrous oxide fed.
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.
NGK V-Power spark plugs are available for most American and Import cars and light trucks.
NGK Platinum Spark Plugs
NGK is the largest original equipment supplier of platinum spark plugs in the world. Companies like General Motors, Honda, Nissan, Toyota, and others all specify NGK Platinum Spark Plugs as standard equipment.
Today, all of the U.S. automakers have begun to specify platinum spark plugs as original equipment. Platinum spark plugs last much longer than conventional spark plugs and perform more consistently over the course of their service life.
While platinum is an extremely durable material, that durability comes with a price. Platinum is an expensive precious metal, costing in the neighborhood of $400 an ounce. At NGK we use a large amount of platinum in our spark plugs. That large amount of platinum is naturally going to cost more. We think it's worth it.
NGK Iridium Spark Plugs
Iridium is a precious, silver-white metal and one of the densest materials found on earth. The natural properties of Iridium offered NGK the opportunity to create one of the world's finest spark plugs. The result are spark plugs that require less voltage to spark, burns fuel more efficiently, sparks at leaner air/fuel mixtures, and delivers higher horsepower and better gas mileage.
NGK offers two choices of this precious metal plug:
The Iridium - A high quality iridium plug installed as original equipment (OE) in the automotive industry since 1994, and the new Iridium IX® - The ultimate evolution of a performance spark plug.
