With their optimized winding design, PerTronix Flame-Thrower HEI and TFI ignition coils are a great upgrade from stock. They produce more than 50,000 V of energy to zap your plugs, for fuller, more complete combustion and better power. When used with their companion Flame-Thrower ignition modules, they produce more than twice the energy of a stock system at the plugs. They're wrapped in rugged alkyd housings and are available for both distributor-mounted and external applications.
