Product Details
When you're pushing your engine to its limits on the track, you need spark plugs that can keep up. These NGK Iridium Racing spark plugs are built specifically for those grueling racing conditions where reliability and consistent spark are critical. They're designed to handle the extreme heat and pressures found in high-performance racing applications.
The center electrode on these plugs features a fine wire design made from an iridium alloy, which has a very high melting point. This construction ensures durability and a stable spark, even under intense engine loads. The copper core helps manage heat, and the triple seals prevent any leaks, making them a solid option for serious racing use.
