Spark Plugs

Description

The NGK IFR9H11 Laser Iridium Spark Plug is designed for durability and high performance. It features a fine iridium tip for a stable spark, superior acceleration, fuel efficiency, and longevity. The ultra-small-diameter center electrode reduces voltage requirements and extends ignition system life. A trivalent metal plating enhances resistance to corrosion and seizing, while the high-grade pure alumina ceramic and 98% pure copper core help prevent overheating. Engineered as an OE or equivalent replacement, this spark plug is ideal for vehicles originally equipped with fine-wire iridium alloy plugs.
