NGKR5671A-7 - NGK V-POWER RACING SPARK PLUG GASKET SEAT NO RESIST HEAT RANGE 7

NGK's V-grooved center electrode moves the spark to the outer edge of the electrode for improved ignitability in all combustion chamber conditions. This configuration is especially helpful for throttle responsiveness, quicker corner exits, and more power on the bottom end in a drag race engine.

NGK V-Power Racing Spark Plugs are available in a wide variety of heat ranges to fit most drag race, circle track or road racing applications. The high-purity alumina silicates used in the insulators of NGK Spark Plugs helps keep the spark plug tip warm enough to burn off deposits at low-speed, yet still be able to transfer enough heat during high-speed operation to prevent detonation and pre-ignition
