Bosch YR6KI332S Iridium Spark Longer Review

Bosch original equipment design, materials and processes represent advanced OE technology that delivers both high performance and long life. The fine wire design of the center electrode improves ignitability and performance in your engine while the Iridium center electrode and Iridium-Platinum tipped ground electrode provides an extended service life. Ribbed insulator design seals tightly against the wire boot preventing misfires due to flash-over. Nickel-plated rolled threads provide superior resistance to corrosion and do not require anti-seize for installation. Bosch Iridium spark plugs are pre-gapped at the factory and do not require a gap adjustment prior to installation.
