DENSO SPARK PLUG W31ES-U (B10ES)

W31ES-U (B10ES)

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, channelled 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
around 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 radio
interferences.*All-round electronic 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)
