■Product Description
Role of Ignition Coils
In internal combustion engines using spark plugs, a high voltage of 20,000 to 35,000V is required to cause a discharge in the combustion chamber during the compression stroke. An ignition coil is a type of transformer that converts 12V battery voltage into the high voltage required for spark plug discharge. It basically consists of a primary coil, a secondary coil, and a core (iron core), and epoxy resin is filled in the case to ensure insulation between these components.

High Voltage Generation Principle of Ignition Coils
There are various types of ignition coils, differing in external shape, number of output terminals, etc., but the high voltage generation principle is all the same. 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 field lines called magnetic flux in the core (iron core) that serves as the axis of the primary coil, and the core (iron core) becomes 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) is no longer 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 generate high voltage by increasing the winding of the secondary coil.
Type: Pencil Coil [1-Output Type]
Ignition coils are installed directly on each spark plug, so no spark plug wires are required. This is currently the most commonly adopted type by automobile manufacturers.

■Precautions
1. Always turn off the engine before inspecting or replacing.
2. Please check for any oil adherence or leakage around the plug hole. Oil adherence or leakage can cause malfunctions.
3. Perform inspection and replacement according to the service manual of each automobile manufacturer.
4. Please handle the connector carefully when attaching and detaching. Damaging the connector part can lead to poor conductivity or other issues.
5. Do not use a product that has been dropped, as dropping it or subjecting it to impact may cause cracks or damage to internal components.
6. Please use the ignition coil with the correct part number as stated in this document.
7. Do not use the ignition coil in this document for purposes other than its intended use.
8. When storing, avoid high temperatures and humidity.
9. When 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. Failing to clear the error code may lead to problems such as the engine check lamp not turning off.
