Over sustained thermal cycling in the compact engine bay of the \u003cstrong\u003eV45W\u003c\/strong\u003e and \u003cstrong\u003eV75W\u003c\/strong\u003e chassis, the factory coil casing epoxy degrades. This leads to internal primary-to-secondary winding shorts and external dielectric breakdown. Simultaneously, high electrical demand erodes conventional plug electrodes, widening plug gaps and requiring higher secondary voltage that overheats the factory coils. The result is unburned fuel, hesitation under load, carbon fouling, and recurring P0300-P0306 diagnostic trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement kit pairs three dual-tower ignition coils with six fine-wire iridium spark plugs engineered to exceed OE endurance thresholds. The replacement coils feature high-temperature vacuum-potted epoxy insulation and low-resistance copper core windings to withstand thermal saturation and prevent high-voltage arcing. The matched iridium plugs feature laser-welded 0.6mm fine-wire center electrodes, drastically reducing required firing voltage while providing superior anti-fouling capabilities and corrosion resistance against combustion chamber thermal shock.\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; 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;\"\u003e1997-2002 Mitsubishi Montero\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;\"\u003e\n\u003cstrong\u003e6G74\u003c\/strong\u003e 3.5L V6 \/ \u003cstrong\u003eV45W\u003c\/strong\u003e, \u003cstrong\u003eV75W\u003c\/strong\u003e\n\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 \/ 228 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;\"\u003e\n\u003cstrong\u003eMD314582\u003c\/strong\u003e, \u003cstrong\u003eUF196\u003c\/strong\u003e, \u003cstrong\u003eUF197\u003c\/strong\u003e, KIN133726TOP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1997-2000 Mitsubishi Montero LS, SR (3.5L V6 6G74 SOHC, Chassis V45W)\u003c\/li\u003e\n  \u003cli\u003e2001-2002 Mitsubishi Montero XLS, Limited (3.5L V6 6G74 SOHC, Chassis V75W)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the V45W and V75W Montero?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1997-2002 Mitsubishi Montero equipped with the \u003cstrong\u003e6G74\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo these iridium spark plugs require gapping prior to installation?\u003c\/strong\u003e\u003cbr\u003e No, the iridium spark plugs are factory pre-gapped, and manual adjustment is not advised as it can fracture the brittle fine-wire electrode.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mitsubishi Durability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle the extended low-speed crawling and heavy towing demands of genuine four-wheel-drive platforms, this ignition system ensures consistent, high-load arc stability across rough terrain and harsh ambient conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50594424455416,"sku":"DS-E8K9TM9B1","price":79.95,"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-mitsubishi-montero-1997-2002-3-5l-1.jpg?v=1790058873","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-mitsubishi-montero-1997-2002-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
