Enhance your vehicle’s ignition performance with the NGK Laser Iridium Spark Plugs, engineered to meet and exceed OE standards. These plugs are designed for direct-fit applications, offering exceptional reliability and long-lasting performance for models such as the 2006 Mitsubishi Lancer and 2019–2020 Subaru WRX STI.
Featuring an iridium-tipped center electrode, these spark plugs deliver up to six times the durability of traditional platinum plugs, providing consistent ignition and superior throttle response. The high-grade pure alumina ceramic construction improves heat dissipation and prevents pre-ignition, while the 98% pure copper core ensures optimal thermal conductivity for stable combustion under demanding conditions.
A platinum pad on the ground electrode helps reduce wear and maintain precise spark gaps, making these plugs ideal for distributorless ignition systems. Tested to rigorous NGK standards, the Laser Iridium series combines durability, efficiency, and performance—perfect for both daily driving and spirited applications.
Whether you’re performing routine maintenance or upgrading your ignition system, these NGK spark plugs provide the dependable spark and longevity your engine deserves.
