Brisk iridium racing spark plugs increase your engine power. Iridium is 6 times harder, 8 times stronger, and has a 1,200 degrees higher melting point than platinum. These plugs are power-focused, putting the spark exactly in the focal point of the reflector. They require lower supplied ignition voltage, and are built with an optimized diameter center and cut back ground electrode. Iridium spark plugs are ideal for high-pressure, high-output race engines, as well as turbo, supercharged, or nitrous applications. Additional product details: * Less quenching, better air/fuel mixture access equals more power * Ability to ignite lean mixtures and difficult-to-ignite fuels * Good resistance to fouling and easier starts

NGK Iridium IX spark plugs feature an ultra-fine center electrode that's designed just thick enough to ensure the maximum durability and life of the spark plugs—and just thin enough to create an accurate and consistent spark. They represent the ultimate evolution of spark plug technology and performance. Iridium is the hardest metal used in spark plugs today—six times harder than platinum. This allowed NGK engineers to reduce the voltage requirement for a spark. Iridium IX plugs are available in more than a hundred configurations for universal and vehicle-specific applications.

NGK Laser Iridium spark plugs feature laser-welded technology. Lasers are used to pinpoint precision welds, reducing excess debris; this decreases the required voltage to bridge the spark gap. An iridium disc is welded on the center electrode and a platinum disc is welded on the ground electrode, reducing the wear rate of both surfaces and ensuring great durability and long life. These spark plugs are available for use with a variety of engine types.
