Denso to launch fuel efficient and Eco friendly Sparkplug in Japan
![]()
Denso will launch a fuel-efficient spark plug in the Japanese market on January 6, 2010. DENSO’s new spark plug improves fuel efficiency by 1.2 percent, torque by 1.1 percent, and decreases carbon dioxide emissions by 0.8 percent in comparison with the company’s conventional nickel spark plug. The new spark plug sold under the product name Twin Tip in North America and Europe (including Russia), uses a tip shape for the ground electrode, in addition to the tip shape of the center electrode for conventional spark plugs. This unique structure results in improved ignition performance for a more powerful and fuel-efficient combustion.
The new spark plug also uses a newly-developed material, a nickel alloy, for the ground and center electrodes. This material enables the center electrode to be made 40 percent thinner than that of conventional nickel spark plugs. Denso’s new spark plugs are positioned in the middle of high-performance spark plugs and conventional nickel spark plug in its price and performance.
