Over thousands of heat cycles, the epoxy potting compound inside the OEM coils begins to crack, allowing moisture intrusion and leading to internal arcing. This degrades the primary winding resistance, resulting in weak spark energy, rough idling, hesitation under heavy throttle, and inevitable P0300 series misfire codes. Furthermore, aging factory spark plug electrodes erode over time, increasing the spark gap and forcing the already weakened ignition coils to work even harder to jump the gap, leading to premature ignition module failure.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis comprehensive ignition overhaul kit addresses factory W-body shortcomings by utilizing upgraded materials and ISO\/TS16949 certified manufacturing processes. The three replacement coil packs feature premium copper windings with optimized primary and secondary resistance, ensuring maximum voltage output to the plugs without overheating the ignition control module. High-grade dielectric epoxy potting completely seals the internal components against heat soak and engine bay moisture. Paired with six genuine NGK spark plugs featuring precision-engineered center electrodes, this package guarantees optimal flame kernel growth, cleaner combustion, improved throttle response, and maximum fuel atomization across the entire RPM range.\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;\"\u003e1990-2004 Buick Regal\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;\"\u003e3.1L 60-Degree V6, 3.8L 3800 V6 \/ GM 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;\"\u003e140-240 hp \/ 185-280 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;\"\u003eC849SPEC, 2-5192, EBC1518, GN10123\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e1990 Buick Regal 3.1L V6\u003c\/li\u003e\n    \u003cli\u003e1991 Buick Regal 3.1L V6 \/ 3.8L V6\u003c\/li\u003e\n    \u003cli\u003e1992 Buick Regal 3.1L V6 \/ 3.8L V6\u003c\/li\u003e\n    \u003cli\u003e1993 Buick Regal 3.1L V6 \/ 3.8L V6\u003c\/li\u003e\n    \u003cli\u003e1994 Buick Regal 3.1L V6 \/ 3.8L V6\u003c\/li\u003e\n    \u003cli\u003e1995 Buick Regal 3.1L V6 \/ 3.8L V6\u003c\/li\u003e\n    \u003cli\u003e1996 Buick Regal 3.1L V6 \/ 3.8L V6\u003c\/li\u003e\n    \u003cli\u003e1997 Buick Regal 3.8L V6\u003c\/li\u003e\n    \u003cli\u003e1998 Buick Regal 3.8L V6\u003c\/li\u003e\n    \u003cli\u003e1999 Buick Regal 3.8L V6\u003c\/li\u003e\n    \u003cli\u003e2000 Buick Regal 3.8L V6\u003c\/li\u003e\n    \u003cli\u003e2001 Buick Regal 3.8L V6\u003c\/li\u003e\n    \u003cli\u003e2002 Buick Regal 3.8L V6\u003c\/li\u003e\n    \u003cli\u003e2003 Buick Regal 3.8L V6\u003c\/li\u003e\n    \u003cli\u003e2004 Buick Regal 3.8L V6\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Buick Reliability Standard\u003c\/h3\u003e\n  \u003cp\u003eWhether you are daily driving a naturally aspirated Custom or pushing boost through a supercharged GS, maintaining peak ignition performance is critical for preserving the legendary reliability and smooth power delivery of the GM 3800 and 3.1L platforms.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50066449826040,"sku":"DS-EBP111APZ","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-regal-1990-2004-3-1l-3-8l-v6-1.jpg?v=1785285161","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-spark-plugs-for-buick-regal-1990-2004-3-1l-3-8l-v6","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
