NGK SPARK PLUGS Spark Plug - CPR9EB-9 6508

Spark plug selection directly impacts engine reliability, throttle response, and fuel efficiency—especially under demanding conditions. The NGK CPR9EB-9 delivers a wide thermal operating range that eliminates fouling at low loads and prevents detonation at high boost, making it ideal for both street and track applications. If you're pushing your engine hard, the wrong plug choice will cost you performance and reliability.

The CPR9EB-9 combines proven NGK engineering with materials designed to handle extended heat cycles without degradation. Its deep-seated copper core and nickel alloy tip provide superior longevity while the high alumina ceramic center offers better heat dissipation and electrical insulation—critical for consistent ignition timing across your power band.
