ACCEL's remote-mount coils have optimized low-resistance, high-turns-ratio windings, and an M36 high-silicone-magnetic steel E-core for higher energy and more voltage output. They're a direct performance replacement for stock units and feature highly specialized silicone-magnetic steel cores that, together with these coils' optimized winding resistance and turns ratios, deliver 10-15 percent more energy than Original Equipment Manufacturer coils. Specialized high-temperature epoxy resists shock and vibration and still increases thermal conductivity. These coils come with all mounting hardware.
