Subaru Ngk SILZKAR7B11 - Laser Iridium Spark Plug-4pcs

Laser Iridium spark plugs provide superior ignitability and long service life. The smallest tip diameter available ensures slow wear rate providing stable idle, superior anti fouling, improved fuel efficiency and lower emissionsTHIS NGK Laser Iridium Spark Plugs feature a laser welded iridium center electrode tip which ensures high durability and a greater spark while the platinum disc welded to the backside of the ground electrode provides a longer life. The longer insulator nose prevents fouling, the corrugated ribs on the insulator prevents flashover and the triple gasket seal eliminates combustion gas leakage.
