NGK 4216 R0045Q-10 RACING PLUG(COPPER GASKET)

MFG Part Number: 4216

NGKs wide heat range results from using copper wire in place of the iron cores found in many conventional plugs

Copper dissipates heat quicker, cooling the electrode and insulator tip

Raised pre-ignition rating with high conduction copper and long nose insulator

Each meets the requirements of high-performance engines
