Spark Plug DENSO 5648 VFK20F

The premium DENSO Iridium Tough VFK20F spark plug (part number 5648) is a high-tech solution for modern gasoline engines. The main feature of this model is the combination of an ultra-fine 0.4 mm iridium center electrode and a platinum tip on the ground electrode, which guarantees exceptional wear resistance and a service life of up to 100,000 km. Technical specifications include a 14 mm thread diameter, 19 mm thread length, and a 16 mm hex size. Thanks to 360-degree laser welding technology, the plug provides stable spark formation even under high combustion chamber pressure, improving acceleration dynamics and reducing fuel consumption. The VFK20F model is optimized for a wide range of Japanese and European vehicles requiring enhanced ignition system reliability in extreme temperature conditions. Using this spark plug minimizes misfires and promotes clean exhaust, meeting strict environmental standards.
