Denso Ignition Coil (DIC-0137) Fits: Toyota

The DENSO Difference

In today's low emission, high-efficiency engines the key to effective combustion is consistent, high-energy ignition output. The high voltage required for ignition is provided by the Ignition Coil - a type of transformer that features primary and secondary coils of wire wrapped in layers around an iron core. The role of the Ignition Coil is to transform the low voltage in a car's battery into the thousands of volts which are used by the spark plug to generate sparking. These sparks ignite the air-fuel mixture inside the combustion chamber.
