Denso Ignition Coil Wiring Diagram

Ignition coils are an essential part of any car’s ignition system. They are responsible for converting the battery’s low voltage to the high voltage needed to ignite the fuel in the engine. One of the most popular brands of ignition coils is Denso, which has been in the industry for several decades.

What is a Denso ignition coil?

A Denso ignition coil is a device that is used in a car’s ignition system to produce high voltage required to ignite the fuel in the engine. It is made up of a primary and secondary coil, which work together to generate the necessary voltage. The primary coil is connected to the battery, while the secondary coil is connected to the spark plugs. When the primary coil is energized, it creates a magnetic field that induces a high voltage in the secondary coil, which is then passed to the spark plugs.

Denso ignition coils are known for their high-quality construction and reliability. They are designed to withstand the high temperatures and vibrations of a car’s engine, making them ideal for use in almost any car make and model.
