NGK 9723 SILZKR7B11 Laser Iridium Spark Plug
Laser welded Iridium center electrode tip ensures high durability and greater spark
Platinum disc welded to backside of ground electrode provides long life
Longer insulator nose prevents carbonization, Corrugated ribs on insulator prevents flashover, and the triple gasket seal eliminates combustion gas leakage
Faster starts and quicker acceleration
Better fuel economy and lower emissions, Trivalent Metal Plating for superior anti-corrosion and anti-seizing
Laser Iridium Spark Plugs provide superior ignitability and long service life. Smallest tip diameter available iridium/platinum surfaces ensure slow wear rate providing stable idle, superior anti fouling, improved fuel efficiency and lower emissions.
