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 in the case to ensure insulation between these parts.\u003c\/p\u003e\n\n\u003cp\u003eSpecifications\n\u003cbr\u003eHigh Voltage Generation Principle of Ignition Coils\n\u003cbr\u003eThere are various types of ignition coils, differing in external shape, number of output terminals, etc., but the high voltage generation principle 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, and current flows through the primary coil. This generates a bundle of magnetic field lines called magnetic flux in the core (iron core) which is 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) 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, by electromagnetic induction*, in proportion to the winding ratio of the primary coil and the secondary coil. 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).\n\u003cbr\u003e*A coil has the property of generating voltage when the magnetic flux passing through it changes. This voltage generation phenomenon is called electromagnetic induction.\n\u003cbr\u003eSince the voltage generated in a coil increases in proportion to the number of windings, ignition coils generate high voltage by increasing the number of windings in the secondary coil.\n\u003cbr\u003eType: Pencil Coil [1-output type]\n\u003cbr\u003eIgnition coils are installed directly on each spark plug, so no spark plug wires are needed. This is currently the most commonly adopted type by automobile manufacturers.\n\u003cbr\u003eCompatible manufacturer: Honda\n\u003cbr\u003eCompatible genuine part number: 30521-RBJ-S01\n\u003cbr\u003eCompatible models: Insight (ZE2) [2009\/2-2010\/3] *Rear | Fit (GP1) [2010\/10-2013\/9] *Rear | Fit Shuttle (GP2) [2011\/6-2015\/3] *Rear | Freed (GP3) [2011\/10-2016\/9] *Rear | Freed Spike (GP3) [2011\/10-2016\/9] *Rear\u003c\/p\u003e\n\n\u003cp\u003e■Notes on images\n\u003cbr\u003e*Images are for illustration purposes only.

Always turn off the engine before inspection or replacement.\n\u003cbr\u003e2. Please check for any oil or leakage around the spark plug hole. Oil contamination or leakage can cause malfunction.\n\u003cbr\u003e3. Perform inspection and replacement according to the service manual of each automobile manufacturer.\n\u003cbr\u003e4. Be careful when attaching and detaching the connector. Damaging the connector part can lead to poor electrical conductivity.\n\u003cbr\u003e5. Do not use a dropped product as it may cause cracks or damage to internal components if dropped or subjected to impact.\n\u003cbr\u003e6. Please use the correct ignition coil part number as specified in this document.\n\u003cbr\u003e7. Do not use the ignition coil in this document for any purpose other than its intended use.\n\u003cbr\u003e8. When storing, avoid high temperatures and humidity.\n\u003cbr\u003e9. When the engine check (MIL) lamp illuminates, before (or after) replacing the ignition coil, always clear (reset) the diagnostic (self-diagnosis\/OBD) error code according to the service manual or similar. Failure to clear the error code may lead to problems such as the engine check lamp not turning off.\u003c\/p\u003e","brand":"日本特殊陶業(NGK)","offers":[{"title":"Default Title","offer_id":46119128039659,"sku":"ngk-u5267-48883","price":6122.0,"currency_code":"JPY","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0689\/1021\/9499\/files\/ngk-ignition_0193be1a-7ac0-4b41-8ad7-527d51ab578d.jpg?v=1737445173","url":"https:\/\/bikeman.jp\/en\/products\/ngk-u5267-48883","provider":"バイクマン","version":"1.0","type":"link"}
