Bosch 7321 FR3KII332 0242225511 Industrial Plug

High content iridium center electrode and platinum ground electrode for long life in natural gas applications. Continuous laser welding ensures precious metal stays in place. Extra material in thread area helps control shell deformation under torque while specially engineered crush washer offers high torque retention. Nickel plated threads reduce likelihood of seizing. Longer graphite-metal glass resistor provides consistent resistive value for EIS equipped engines. Gas tight seal prevents blow by of combustion gasses. Full length threaded and crimped brass terminal nut provides maximum strength and secure vibration free connection to ignition leads.
