The NGK Iridium IX spark plug is aimed at performance-minded drivers seeking improved throttle response, economy and ignitability. A fine iridium center electrode provides long-lasting spark consistency while the tapered-cut ground electrode enhances starting and idle behavior. Trivalent metal plating reduces corrosion and seizing, making this plug a durable upgrade from OE nickel alloy spark plugs in modified or higher-output engines.
