The NGK Single Iridium (Iridium IX) spark plug is a fine-wire, high-durability option that enhances ignition consistency and throttle response. An iridium center electrode offers markedly improved ignitability and longer tip life than platinum, while trivalent plating protects against corrosion. Recommended for modified or high-performance applications, it serves as a durable upgrade to standard nickel plugs.
