Brisk Silver Racing Spark Plugs are the ultimate spark plug for your Mustang! These spark plugs are perfect for high compression, forced induction, and nitrous applications where maximum spark energy is required. Unlike copper, platinum, or iridium designs, Brisk spark plugs feature a fine wire Silver center electrode, cut-back side ground electrode, and high dielectric strenght insulator for superior ignitability, low ignition voltage requirements, and high dielectric strength.

What does that mean to you? It means you get a stronger, more intense spark for improved power and gas mileage!
