Hitachi's ignition coils are designed and built to meet the stringent specifications of OE manufacturers around the world. Constructed with high quality materials and assembled in state of the art facilities, Hitachi's ignition coils produce plenty of energy for today's high efficiency engines. With greater turn ratios than other leading brands, Hitachi's ignition coils are capable of producing 35,000+ volts to create a more complete burn, resulting in better fuel economy, more power and lower emissions. Not overlooking the details, Hitachi welds all of the electrical contacts within the ignition coil to ensure durability and longevity versus soldered connections. Internal capacitors also keep electrical noise generated by the coils in check. Designed to meet the exact needs of each specific vehicle, Hitachi ignition coils are the premium choice.
