They develop all of their ranges in-house, and manufacture them in their own ISO9000 certified factories worldwide - with 'zero defects' as standard. They also provide this outstanding OE quality to the aftermarket. Including Standard, Platinum and Iridium, DENSO Spark Plugs cover a complete range of continually updated references. Guaranteeing optimum engine performance, choose DENSO Spark Plugs for every automotive, motorcycle, marine and small engine application.

DENSO's Twin Tip Plugs use a tip shape for the ground electrode, in addition to the tip shape of the centre electrode for conventional spark plugs. This unique structure results in improved ignition performance for a more powerful and fuel-efficient combustion. The nickel alloy contacts enables the centre electrode to be made 40 percent thinner than that of conventional nickel spark plugs. When the spark generated by a spark plug grows during combustion with the air-fuel mixture, it loses heat when it comes into contact with electrodes and ignition performance decreases. Thinner electrodes result in less obstruction of spark growth (quenching), meaning better ignitability.
