BOSCH Spark Plug - VR6NII352U

Electrode Material: Iridium center electrode, Nickel ground electrode

Ultra fine wire center electrode and ground electrode increase ignitability and reduce spark quenching. Double iridium tipped center electrode and platinum tipped ground electrode promote durability and long life. Copper core helps prevent pre-ignition and fouling. Nickel-plated shell and rolled threads provide anti-seize and corrosion protection. Ribbed insulator prevents flashover
