Bosch Auto 96323 Bosch Double Iridium Pin-to-Pin

Double Iridium electrodes – iridium-alloy firing pin and an iridium-alloy pin laser-welded onto the ground electrode offer higher performance and up to 4 times longer life compared to standard copper spark plugs. OE Fine Wire design requires up to 24% less voltage to ignite. 360 degree continuous laser welding increases durability for increased life. Copper core provides broader heat range to resist pre-ignition and fouling. Bosch Iridium Spark Plugs are engineered to deliver both high performance and long life, representing the best of OE spark plug technology. Bosch Double Iridium Pin-to-Pin technology features 2 iridium-alloy electrodes – an iridium-alloy firing pin and iridium-alloy pin laser-welded onto the ground electrode. This design offers higher performance by allowing more efficient flame-kernel growth and up to 4 times longer life compared to standard copper spark plugs.
