NICKEL SPARK PLUGS


MORE THAN A "STANDARD" SPARK PLUG!
U-Groove is an innovative design that helped to make DENSO spark plugs famous. The plug employs a unique, channeled ground electrode designed to generate a larger spark nucleus at the point of ignition.
U-GROOVE TECHNOLOGY
Improved Ignition, fuel saving, engine and emissions performance
*Better fuel economy: U-groove Spark Plugs can ignite leaner mixtures; therefore reducing misfires.*Smoother running: the spark and the flame are not crushed between the electrodes giving the flame front more space; thus increasing engine performance.*Efficient combustion: The "U" shape allows the spark to fill the gap; creating an efficient combustion.*Lower emissions: U-groove combines the advantage of a bigger gap, while maintaining a standard space.*Durability: The "U-groove" shape is located on the ground electrode (as opposed to the centre electrode); the area the least affected by wear and tear to ensure a maximum lifespan.
RESISTOR SPARK PLUG
Intelligent design to minimise radio interferences
*High quality Resistor: our full range of resistor plugs feature a metal sleeve artound the insulator and a protected connection point, to avoid potential interference with electronic equipment.*Reduces radio interferences: resistors located in the spark segment of the plug greatly reduce radiom interferences.*All-round electronicx systems performance: Resistors also avoid interferences with other electronic equipment including mobile telephones, ignition and management systems, ABS and navigation systems.
HEAT RANGE
The best heat range performance on the market
*More heat ranges: DENSO spark plugs cover more heat ranges than any other manufacturers without compromise on quality and performance; ensuring the right choice for almost every application, with optimal engine performance.*Less stock: Fewer part numbers to cover all heat ranges means less stock holding.*Ideal operating temperature: The unique design of DENSO Spark Plug helps channelling the ideal amount of heat out of the combustion chamber, ensuring DENSO plugs run neither too hot (causing pre-ignition), nor too cold (causing carbon fouling)
