Denso to release a fuel-saving spark plug

Denso will release a fuel-efficient spark plug into 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 lowers CO2 emissions by 0.8 percent by comparison to the company's conventional nickel spark plug. The new product, which has been sold under the product name "Twin Tip" in North America and Europe, 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 improves ignition performance allowing for a more fuel-efficient combustion.
