Product Details

The fine iridium center electrode in these NGK Iridium IX spark plugs is six times harder than platinum, offering exceptional durability and a consistent spark. This advanced material choice is perfect for today's higher-temperature engines, helping to improve acceleration, fuel efficiency, and overall engine longevity. These plugs are a great upgrade over standard nickel alloy options, especially for modified or performance-oriented applications.

NGK's Iridium IX plugs are built with a tapered cut ground electrode, which helps with easier starting, smoother idling, and improved throttle response. The trivalent metal plating on the plug body provides excellent resistance to corrosion and makes them easier to remove later on, preventing seizing. This box contains four spark plugs, making it convenient for many common engine configurations.
