NGK Laser Platinum spark plugs are engineered to meet original equipment standards for high ignitability and extended service life. These plugs feature a laser-welded platinum pad on the ground electrode to ensure even wear and consistent performance in modern distributorless ignition systems. Designed specifically for SRT and Scat Pack Hemi applications, they provide stable idling, superior anti-fouling characteristics, and improved thermal management.

The construction includes a 98% pure copper core for maximum heat dissipation and a high-grade alumina silicate ceramic insulator for superior dielectric strength. To ensure long-term reliability in harsh engine bay environments, the shell is treated with trivalent metal plating for anti-corrosion and anti-seizing properties.
