Over time, high thermal load degrades the primary and secondary copper windings, causing dielectric puncture, micro-arcing, intermittent misfires under heavy throttle load, rough idle, and unburned fuel dumping into the catalytic converters. Standard copper plugs also experience rapid gap erosion, placing excessive voltage demand on aging coils.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive tune-up kit features six heavy-duty ignition coil packs manufactured with high-grade internal copper windings, reinforced thermoplastic housings, and corrosion-resistant blade terminals for maximum conductivity and thermal stability. Paired with six fine-wire iridium spark plugs, the system provides a concentrated spark kernel, superior anti-fouling resistance, lower required firing voltage, and stable combustion under high engine load.\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;\"\u003e2005-2008 Jeep Grand Cherokee\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;\"\u003e3.7L PowerTech V6 (EKG) \/ WK Chassis\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;\"\u003e210 hp \/ 235 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;\"\u003eUF270, 56028138AF, ZFR6FGP, UF297, UF399\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2005 Jeep Grand Cherokee 3.7L V6 (Laredo)\u003c\/li\u003e\n  \u003cli\u003e2006 Jeep Grand Cherokee 3.7L V6 (Laredo)\u003c\/li\u003e\n  \u003cli\u003e2007 Jeep Grand Cherokee 3.7L V6 (Laredo)\u003c\/li\u003e\n  \u003cli\u003e2008 Jeep Grand Cherokee 3.7L V6 (Laredo)\u003c\/li\u003e\n  \u003cli\u003eInterchange OE: UF270, UF-270, 56028138, 56028138AB, 56028138AD, 56028138AE, 56028138AF, UF297, UF399, ZFR6FGP, 52-2034, 5C1114, E232, 178-8483\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Jeep Durability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle off-road vibration, high ambient engine bay temperatures, and steep grade towing demands, this ignition package delivers consistent high-voltage discharge to ensure smooth idle and reliable torque delivery across rough terrain.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50451864420600,"sku":"DS-E86ZTJW4E","price":81.95,"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-jeep-grand-cherokee-2005-2008-3-7l-1.jpg?v=1788711697","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-jeep-grand-cherokee-2005-2008-3-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
