NGK Racing Spark Plugs are
designed to improve the performance of your vehicle. They
are constructed from durable material that is corrosion and abrasion
resistant. The spark plugs feature fine-wire center electrodes which
provide better sparking and ignitability. They also use metals
such as platinum, gold palladium as electrode material to improve
durability and lower voltage requirements. And the special insulator
configuration improves throttle response.
