25,000-Volt ignition coil packs increase power to the spark plug by as much as 25% over stock and are designed to be a direct OEM replacement. They exceed OEM specifications, are OBD-II computer safe and feature silicone magnetic steel core technology. By optimizing the winding process and decreasing overall material diameters, GMS was able to increase the spooling process by 20% to achieve a 25% increase in output over the factory coils. Brass secondary contacts assure maximum performance from the coil to the plug every time.
