Over time, OEM coil packs succumb to heat soak from the cast-iron block and aluminum heads, degrading the internal epoxy and copper windings. This thermal breakdown causes inconsistent voltage, manifesting as a rough idle, hesitation under heavy load, and P0300-series misfire codes. Furthermore, standard plugs wear their electrodes rapidly under high combustion pressures, widening the spark gap and delaying the critical flame front propagation required for complete cylinder detonation.\u003c\/p\u003e\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis ignition kit upgrades Hemi spark delivery utilizing high-grade materials. The performance coils feature premium silicone boots that resist thermal brittleness and prevent voltage arcing. Internal primary and secondary copper windings are engineered for higher kilovolt (kV) output and rapid recharge times, ensuring a potent spark even at high RPMs. Paired with 16 iridium spark plugs—two per cylinder as required by the Hemi architecture—the ultra-fine center electrodes maintain a precise gap over a significantly extended lifespan. This combination promotes a highly concentrated spark that vaporizes fuel efficiently, stabilizing idle, recovering lost horsepower, and improving low-end throttle response.\u003c\/p\u003e\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;\"\u003e2005-2022 Chrysler 300\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;\"\u003e5.7L Hemi V8 \/ LX\/LD\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;\"\u003e340-363 hp \/ 390-394 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;\"\u003eUF504, 56029129AA, 68060346AA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2005-2022 Chrysler 300 5.7L V8\u003c\/li\u003e\n\u003cli\u003e2005-2022 Chrysler 300 6.1L V8\u003c\/li\u003e\n\u003cli\u003e2005-2022 Chrysler 300 6.4L V8\u003c\/li\u003e\n\u003cli\u003eInterchange Part Numbers: CUF504, UF-504, UF504, 7805-1355, 7805-8103, 2505-302202, 5C1569, 302202, 2505-302202, C1526, E1004, 50090, 52-1828, GN10352, CLS1087, 56029129AA, 56029129AB, 56029129AF, 68060346AA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eThe Chrysler Muscle Standard\u003c\/h3\u003e\n\u003cp\u003eDesigned for the heavy-hitting demands of modern American muscle, this ignition overhaul ensures your Hemi delivers uncompromised power, aggressive throttle response, and robust daily reliability.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48266578198776,"sku":"DS-EQSYVFM67","price":179.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-chrysler-300-2005-2022-5-7l-6-1l-6-4l-v8-1.jpg?v=1776822952","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-iridium-spark-plugs-for-chrysler-300-2005-2022-5-7l-6-1l-6-4l-v8","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
