■Product Description
Role of the Ignition Coil
In an internal combustion engine using 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 spark plug discharge. It basically consists of a primary coil, a secondary coil, and a core (iron core), and epoxy resin is filled into the case between these parts to ensure insulation.

Principle of High Voltage Generation in Ignition Coils
While there are various types of ignition coils, differing in external shape and number of output terminals, the principle of high voltage generation is the same for all. 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 creates a bundle of magnetic field lines called magnetic flux in the core (iron core), which is 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) 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*, in proportion 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 spark plug gap, igniting 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.
Also, 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 automotive manufacturers.

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