NGK Laser Iridium Spark Plugs provide superior ignitability and long service life. OE Direct Replacement Spark Plugs - Intended for ALL Power Goals
PRODUCT IS A SINGLE SPARK PLUG, PRICING IS FOR (1) QTY. NOTE: 2006 Impala & Monte Carlo: TR55/IX Compatible with 5.3L V8 only. Please check your application carefully before purchasing these spark plugs - they may not be applicable to your vehicle as they are more of a generic type of product. Be extremely careful when gapping the plugs due to the Iridium center electrode.Ĭhoose your plug type and number of cylinders from the selection box below. 060 as a baseline for your modified engine and tuning from there for your specific car. We recommend leaving the Iridium IX plugs gapped at. According to NGK, the Iridium IX should last longer than the V-Power Tr-55 and you'll also be able to open the gap up for better performance. A level that is expected from the world leader in spark plugs. NGK's new Iridium IX is the personification of these qualities and takes premium performance spark plugs to a new level. It's just the right size to reduce the voltage required for spark and to maximize the overall longer life qualities of iridium.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. The electrode is not too thin and not too thick. And it's in the design of the iridium tip that makes Iridium IX a better spark plug. The fine electrode tip is engineered for greater ignitability. Iridium allows for a center electrode 75 percent the size of a platinum electrode and 24 percent the size of a conventional nickel electrode. NGK Iridium Spark Plugs represent the ultimate evolution of spark plug technology and performance. It may be time to invest in precious metal futures. Is virtually pure to insure dielectric and physical strength, as well as heat transfer away from the tip for maximum performance.Įliminate flashover, which can cause misfiring and engine damage, especially in damp environments. Zinc Chromate Coating Double-dipped for maximum protection. This allows the spark to more quickly ignite the mixture, providing more complete combustion. Other manufacturers use a copper coated center core.įorces the spark to the outer edge of the ground electrode, placing it closer to the air/fuel mixture. Produces a more powerful spark with less firing voltage. Most other manufacturers only use two seals. Virtually eliminates the possibility of combustion gas leakage through the shell. Here are some of the features of this plug: 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. These emissions are not only damaging to the environment, they can reduce the life of expensive catalytic converters and oxygen sensors. More complete combustion not only provides more power, it also means less harmful emissions. What this does is allow the spark to more quickly ignite the mixture, providing more complete combustion. 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. 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 electrode on the market today. 
Modern lean-burning, fuel efficient engines create a new set of requirements for spark plugs.
