【EXTENSIVE 2.0L/2.4L COMPATIBILITY】 Specifically engineered for the "World Engine" platform. Fits Jeep Compass/Patriot (07-17), Dodge Journey (09-17) 2.4L, Avenger (08-14), Caliber (07-12), and Chrysler 200 (11-14) / Sebring (07-10). A direct replacement for OEM UF557, 4606824AB, and 4606824AC. 【100% PURE COPPER: 35kV+ OUTPUT】 Stop the high-speed stuttering caused by cheap aluminum-core coils. Our UF557 ignition coil features high-purity oxygen-free copper windings, delivering 15% more spark energy and a stable 35kV+ voltage. It effectively resolves sluggish acceleration and ensures smooth ignition at any RPM. 【OIL-RESISTANT SILICONE BOOTS】 Eliminate arcing and misfires. Unlike generic rubber boots that swell and soften when exposed to engine oil vapors, our 4606824AB coil pack is upgraded with aviation-grade silicone. It remains structurally sound and dielectric, preventing high-voltage leaks that trigger the P0300 code. 【VACUUM-SEALED EPOXY】 Engineered for extreme thermal cycles. We use a vacuum-sealing process with epoxy to ensure a 100% bubble-free interior. This prevents micro-cracks from 150°C heat or freezing cold-starts, providing a permanent Jeep Patriot misfire fix that lasts for years. 【STOP CHECK ENGINE LIGHTS】 Clear P0300 misfire codes for good. Precision-engineered for seamless ECU communication, our UF557 coils eliminate electrical interference to keep your dashboard warning-free and your engine running smooth. The Permanent Cure for Your Jeep & Dodge Idle Struggles Is your 2.4L engine shaking at stoplights or hesitating when you merge onto the highway? On the Chrysler/Jeep/Dodge platform, a failing ignition coil is the first culprit behind a rough idle and the dreaded P0300 misfire code. Don't settle for a ""temporary fix"" with low-grade aftermarket coils. The RANSOTO High-Performance UF557 Ignition Kit is designed for drivers who demand OEM-plus reliability. We’ve addressed the weaknesses of standard coils by upgrading the core to 100% oxygen-free copper and using vacuum-potted German epoxy. This combination ensures your spark remains hot and consistent, even under the 150°C temps of a crowded engine bay. With our oil-resistant silicone boots, you won't have to worry about oil leaks ruining your ignition performance. Whether you're commuting in a Chrysler 200 or exploring in a Jeep Patriot, upgrade to the ignition parts that work as hard as your ""World Engine"" does. Clear that CEL and get back the power you’ve been missing.
