NGK Iridium IX spark plug (box of 4) provides durable ignitability and improved throttle response for modified or high-performance use. The fine iridium center electrode resists wear and maintains consistent spark delivery while a tapered ground electrode enhances starting and idling. Trivalent metal plating adds corrosion and anti-seize protection, making these plugs a reliable upgrade from standard nickel alloy replacements.
