Description

NGK Laser Platinum spark plugs provide high ignitability and longer service life compared to conventional nickel spark plugs. Laser Platinum plugs are tested to the highest standards to ensure quality and durability. Engineered specifically for OE applications. Laser platinum plugs provide stable idling, superior anti-fouling, improved fuel efficiency and lower emissions. High-grade pure alumina ceramic and 98% pure copper core prevents spark plug from overheating and provides reliable starts. Most Laser Platinum spark plugs feature a platinum pad on the ground electrode for even wear in distributorless ignition systems.
