Accel 140013 Brute Thunder HEI In-cap Super Coil PRE4_G4IQH45

Accel brute thunder hei super-coils are engineered to be the highest-output hei in-cap ignition coils available and are a direct performance replacement for stock units. These coils feature highly specialized silicone-magnetic steel cores that, together with their optimized winding resistance and turns ratios, deliver 10-15 percent more energy than original equipment manufacturer coils. Accel brute thunder hei super-coils are compatible with both original hei ignition systems and later model computer-controlled systems. Specialized high-temperature epoxy resists shock and vibration and still increases thermal conductivity. Mounting screws and a ground strap, silicone coil gasket, and low-ohm contact brush/spring are included.
