#DENSO SPARK PLUG W22M-U (BM7A) (NLA)

DENSO 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.

Features

• Improved Ignition, fuel saving, engine and emissions performance.
• Better fuel economy: U-groove Spark Plugs can ignite leaner mixtures; reducing misfires.
• Smoother running: the spark and the flame are not crushed between the electrodes giving the flame front more space; 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.
• 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.
• All-round electronic systems performance: Resistors also avoid interferences with other electronic equipment including mobile telephones, ignition and management systems, ABS and navigation systems.
