Factory coil cassettes degrade under repeated heat cycling, causing micro-fracturing in the outer casing and breakdown of the internal potting compound. Once dielectric integrity is lost, high-voltage spark energy arcs to the cylinder head rather than the plug gap, triggering intermittent misfires (DTC \u003cstrong\u003eP0300\u003c\/strong\u003e through \u003cstrong\u003eP0306\u003c\/strong\u003e), sluggish acceleration, and catalyst damage from raw fuel dump.\u003c\/p\u003e\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\u003cp\u003eThis comprehensive replacement kit replaces both bank-specific ignition coil rails and pairs them with high-efficiency iridium spark plugs. The coil assemblies utilize vacuum-infused, high-dielectric epoxy potting encased in impact-resistant polybutylene terephthalate (PBT) to suppress thermal cracking and resist dielectric punch-through. Matched with fine-wire iridium core electrodes, the system reduces the firing voltage required from the secondary windings, delivering rapid flame-front initiation, superior anti-fouling performance, and stable resistance to spark quench.\u003c\/p\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; margin-bottom: 20px;\"\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e1999-2001 Cadillac Catera\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e3.0L L81 (X30XE) \/ GM V-Platform (Omega B)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e200 hp \/ 192 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eUF278, UF754, 68080580AB, 68242286AA, 68242286AB, KIN119946TOP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e1999 Cadillac Catera Base 3.0L V6\u003c\/li\u003e\n\u003cli\u003e2000 Cadillac Catera Base 3.0L V6\u003c\/li\u003e\n\u003cli\u003e2000 Cadillac Catera Sport 3.0L V6\u003c\/li\u003e\n\u003cli\u003e2001 Cadillac Catera Base 3.0L V6\u003c\/li\u003e\n\u003cli\u003e2001 Cadillac Catera Sport 3.0L V6\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eDoes this fit the GM V-Platform Catera?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1999-2001 Cadillac Catera equipped with the 3.0L L81 engine.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAre the iridium plugs pre-gapped for this application?\u003c\/strong\u003e\u003cbr\u003e Yes, the included iridium spark plugs arrive pre-gapped to factory 0.040-inch specifications for straightforward, drop-in installation.\u003c\/p\u003e\u003ch3\u003eThe Cadillac Precision Caliber\u003c\/h3\u003e\u003cp\u003eEngineered for the demanding tolerances of the European-developed \u003cstrong\u003eGM V-Platform\u003c\/strong\u003e, this complete ignition service assembly restores precise coil resistance curves and secondary voltage saturation, delivering reliable cold starts and clean combustion without CEL illumination.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50606298726648,"sku":"DS-EUSAXO2RE","price":109.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-and-iridium-spark-plugs-for-cadillac-catera-1999-2001-3-0l-1.jpg?v=1790090364","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-cadillac-catera-1999-2001-3-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
