{"product_id":"ignition-coil-1628","title":"Ignition Coil","description":"The Aston Martin 8G43-12A366-AA is a 3-pin ignition coil specifically designed for Aston Martin's V12 engines, including models such as the DB9, DBS V12, Rapide, V12 Vantage, Vanquish, and Zagato, typically from 2005 onwards. This component features a unique, specially wound spring with an integrated solid metal core, believed to contribute to electrical noise dampening and efficient charge transmission to the spark plug. The spring mechanism is permanently attached to the electronic head of the coil pack, making it a single, integrated unit.\n\nWhile some have explored potential cross-compatibility with parts from Lincoln LS or Jaguar S Type models due to shared Ford components, direct interchangeability is cautioned against. Differences in the boots that seal into the cylinder head and the internal springs connecting to the spark plugs mean that simply swapping boots may compromise performance or reliability. For instance, attempting to use a shorter Lincoln LS coil pack boot and stretching its spring could result in a loss of the critical solid core and altered spring setup, potentially affecting the unit's performance in unforeseen ways. Therefore, using the official Aston Martin part is recommended to ensure proper fitment and function.\n\nEvidence suggests that earlier Aston Martin models, specifically those with VINs prior to a certain point in 2006, may have used a 2-pin coil configuration, while this 3-pin version is standard for later models. Proper identification of the required pin count is crucial before ordering. The part number 8G43-12A366-AA supersedes the earlier 4G43-12A366-AA.","brand":"Aston Martin","offers":[{"title":"Default Title","offer_id":52687000666424,"sku":"8G43-12A366-AA","price":167.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661168200.jpg?v=1784879324","url":"https:\/\/store.motormia.co\/products\/ignition-coil-1628","provider":"MOTORMIA","version":"1.0","type":"link"}
