NGK SPARK PLUG DP7EA-9 5629

NGK Spark Plug DP7EA-9 5629. NGK's wide heat range results from using copper wire instead of iron cores, allowing for quicker heat dissipation and cooling of the electrode and insulator tip. Features a raised pre-ignition rating with high-conduction copper and a long nose insulator, meeting the requirements of high-performance engines. Constructed for longer life and optimum performance with corrugated ribs to prevent flashover. Uses pure alumina silicate ceramic insulators for greater strength and better heat transfer, and a copper core aids heat removal and improves durability. Triple sealed to prevent interior leakage.
