Product Details
If you're building a high-performance engine for track use or serious competition, you need spark plugs that can handle the heat and stress. These NGK Iridium Racing spark plugs are specifically made for those demanding situations, ensuring reliable ignition when it matters most.
The center electrode on these plugs features a fine wire design using an iridium alloy, which has a very high melting point. This construction is key to their durability and ability to maintain a stable spark even under extreme operating conditions. The trivalent metal plating on the plug body helps prevent corrosion and seizing, making installation and future removal much easier, which is a practical benefit when you're working on a race car.
Each plug also includes a pure alumina silicate ceramic insulator for strength and effective heat transfer, along with triple seals to prevent any leaks. This well-built design ensures they can withstand the rigorous demands of racing venues worldwide.
