PS91 performance ignition coils feature FAST's special E-core design, which loses less voltage, so more spark gets to your plugs. The coils also have large-gauge wire windings for maximum spark current and voltage, with better heat dissipation at high rpm. An insulated connector and high-tension tower protect against high-voltage arcing. They're also solid-epoxy encapsulated for shock and vibration protection.
