■Product Description
The role of an ignition coil
In an internal combustion engine that uses spark plugs, a high voltage of 20,000 to 35,000V is required to discharge electricity in the combustion chamber during the compression stroke. An ignition coil is a type of transformer that converts the 12V battery voltage into the high voltage necessary for the spark plug to discharge. It basically consists of a primary coil, a secondary coil, and a core (iron core), and epoxy resin is filled into the case to ensure insulation between these parts.

High voltage generation principle of ignition coils
There are various types of ignition coils, differing in external shape and number of output terminals, but the principle of high voltage generation is the same for all of them. The primary coil is connected to the battery via an igniter (switch). First, the ECU (Engine Control Unit) turns the igniter ON, allowing current to flow through the primary coil. This generates a bundle of magnetic lines of force, called magnetic flux, in the core (iron core) that acts as the axis of the primary coil, making the core (iron core) an electromagnet. Then, when the ECU determines the engine ignition timing, it switches the igniter to the OFF state, stopping the current to the primary coil. As a result, the core (iron core) ceases to be an electromagnet, and the magnetic flux inside the core (iron core) also disappears. When the magnetic flux inside the core (iron core) suddenly disappears, a high voltage is generated in the secondary coil, which shares the same core (iron core) as its axis, due to electromagnetic induction*, according to the turns ratio of the primary and secondary coils. The high voltage generated in the secondary coil causes a spark to jump across the gap of the spark plug, leading to the combustion of the air-fuel mixture (gasoline + air).
*A coil has the property of generating voltage when the magnetic flux passing through it changes. This voltage generation phenomenon is called electromagnetic induction.
Furthermore, since the voltage generated in a coil increases in proportion to the number of turns, ignition coils increase the winding of the secondary coil to generate high voltage.
Type: Pencil coil [1-output type]
Ignition coils are directly attached to each spark plug, so spark plug wires are not necessary. This is currently the most commonly adopted type by automobile manufacturers.

■Precautions
1. Always turn off the engine before inspection or replacement.
2. Please check around the plug hole for any oil adhesion or leakage. Oil adhesion or leakage can cause malfunction.
3. Perform inspection and replacement according to the service manual of each automobile manufacturer.
4. Handle the connector with care when attaching and detaching. Damage to the connector can lead to poor conductivity.
5. Do not use a product that has been dropped, as dropping or impacting it may cause cracks or damage to internal components.
6. Please use the correct part number ignition coil specified in this document.
7. Do not use this ignition coil for any purpose other than its intended use.
8. When storing, avoid high temperatures and humidity.
9. If the engine check (MIL) lamp illuminates, be sure to clear (reset) the diagnostic (self-diagnosis/OBD) error code before (or after) replacing the ignition coil, according to the service manual, etc. Failure to clear the error code may lead to problems such as the engine check lamp not turning off.
