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
