Spark Plug DENSO SK20BGR11 (3472)

The high-tech DENSO SK20BGR11 (3472) spark plug is designed for direct injection engines that require specific ignition characteristics. Its key feature is the high-density iridium alloy on the center electrode combined with a platinum tip, allowing the plug to maintain peak efficiency for over 100,000 km. The design is optimized for high-pressure combustion chamber environments, ensuring rapid flame kernel expansion. Technical specifications include a heat range of 20, a 14 mm thread diameter, and a 1.1 mm gap. This part is an OEM solution for various Toyota models (such as D4 series engines), guaranteeing carbon fouling prevention and stable engine performance at both idle and peak loads.
