100 percent pre-fired to ensure reliable operation
Copper core center electrode for superior thermal conductivity
Developed to meet the demand for improved ignitability, necessary for increased efficiency in emission gas purification and fuel consumption.
Dual copper and glass seal bonds the center electrode and insulator together for a gas-tight seal.
Lasts twice as long as conventional plugs
Unique five-rib insulator reduces flashover and decreases voltage loss
DENSO€™s patented U-Groove spark plug enables complete combustion by allowing the spark to fill the gap created by the U shape. The ball of fire created in the U-Groove develops a larger and hotter flash front that virtually eliminates excessive fouling and erratic starts caused by poor fuel mixtures. Even DENSO€™s €œstandard€ spark plug is something special. The innovative design that helped to make DENSO spark plugs famous, the U-Groove plug employs a unique, channeled ground electrode designed to generate a larger spark nucleus at the point of ignition. Greater spark energy than ordinary plugs means improved flame travel, producing more complete, consistent, and efficient combustion.
