Because the three coil packs sit directly atop the engine block on the Ignition Control Module (ICM), they are subjected to extreme underhood temperatures and continuous heat soak. Over time, this thermal cycling breaks down the internal epoxy potting and primary windings. The result is a weak spark, intermittent misfires under load, rough idling, and decreased fuel efficiency. Additionally, heavily worn standard copper spark plugs can increase the resistance gap, forcing the aging coil packs to work harder and accelerating their inevitable failure.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis ISO\/TS16949 certified ignition kit directly addresses these thermal vulnerabilities by utilizing advanced dielectric epoxy and upgraded magnetic steel cores within the ignition coils. These upgraded materials provide superior resistance to heat soak and ensure consistent voltage output even under extreme engine bay temperatures. The inclusion of six authentic NGK spark plugs guarantees precise spark gap tolerance and optimal combustion efficiency. By replacing the coil packs and spark plugs simultaneously, you reduce the electrical strain on the ICM, ensuring complete fuel burn, restoring throttle response, and eliminating the dreaded P0300 series misfire codes. The direct-fit design ensures proper alignment with factory harnesses and brackets.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2005-2009 Buick Allure\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eGM 3800 Series III V6 (L26) \/ W-Body\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e200 hp \/ 230 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eC849, 10468391, D545, D555, E530C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2005 Buick Allure 3.8L V6\u003c\/li\u003e\n  \u003cli\u003e2006 Buick Allure 3.8L V6\u003c\/li\u003e\n  \u003cli\u003e2007 Buick Allure 3.8L V6\u003c\/li\u003e\n  \u003cli\u003e2008 Buick Allure 3.8L V6\u003c\/li\u003e\n  \u003cli\u003e2009 Buick Allure 3.8L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Buick Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to maintain the legendary longevity of the 3800 V6, this ignition kit restores the smooth, reliable power delivery required for daily commuting and highway driving, keeping your W-body running without a check engine light.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50066444353784,"sku":"DS-ERC9B4REY","price":109.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-buick-allure-2005-2009-3-8l-v6-1.jpg?v=1785284826","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-spark-plugs-for-buick-allure-2005-2009-3-8l-v6","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
