Brisk Racing Spark Plugs GR12YS Silver (replaces TR7/TR8)

SKU: GR12YS
$9.91
Description: Brisk GR12YS Silver Racing Spark plug is designed for forced induction applications and nitrous applications.

Brisk GR12YS Silver Racing Spark Plug replaces NGK heat range 7 and 8.

Most popular applications are modified Shelby GT500, Cobra, Ford Lightining and Harley trucks.

Recommended for all 13-14 GT500 and 07-12 GT500 over 18psi.

Brisk Silver Racing plugs have a better ignitability than conventional performance spark plugs, and offer better performance and reliability in high boost, nitrous or high compression applications. Silver is an element with the most free electrons, and is the best electrical and thermal (heat) conductor of all metals! Better than gold, copper ...and many times better than Iridium. The Brisk Silver Racing plugs have a fine wire center electrode (not just the tip), which gives more room for insulator between the center electrode and spark plug shell. More insulation results in a durable spark plug with high dielectric strength - the most important spark plug parameter in forced induction applications.

YS projected tip recommended over non-projected S plug.
