Spark Plug NGK 3116 IZFR6B Laser Iridium

The premium NGK Laser Iridium IZFR6B spark plug (part number 3116) is designed to provide maximum performance and durability for modern gasoline engines. The laser-welded iridium-tipped center electrode has an extremely high melting point, ensuring a stable spark gap throughout its entire service life (up to 100,000 km). The design is complemented by a platinum plate on the ground electrode to prevent erosion and corrosion. Technical data: 14 mm thread diameter, 19 mm thread length, 16 mm hex size, and a heat range of 6. This part is original equipment (OEM) for many Mitsubishi and Mercedes-Benz models, ensuring full compliance with factory requirements. The high dielectric properties of the insulator and precise electrode geometry contribute to instant engine response and reduced exhaust emissions.
