NGK SIMR8A9 Laser Iridium Spark Plug

Brand	NGK
Model	SIMR8A9
Size	SIMR8A9

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 fouling, 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.
