BDFHYK Ignition Coil Pack UF557 for Jeep Patriot Compass 2007-2017 — Direct Replacement, Heat‑Resistant PBT/PPO

BDFHYK Ignition Coil Pack UF557 is a direct-replacement ignition coil built to restore reliable spark for compatible Jeep, Dodge and Chrysler models.

If your vehicle shows signs of rough idle, hesitation, or longer crank times, a worn ignition coil can be the culprit. The BDFHYK UF557 coil pack is engineered as a one-to-one replacement for select Jeep Patriot and Compass models (2007–2017) and other Chrysler Group vehicles, matching common OEM part numbers to simplify fitment. It uses durable PBT and PPO materials and the original compatible chip to improve heat and wear resistance so the coil endures under typical driving stress.

How will this coil pack improve my vehicle's starting and running?

Replacing a failing coil with a correctly matched unit like the BDFHYK UF557 restores consistent spark delivery, which helps reduce misfires and unstable idling. Improved spark timing and strength often lead to smoother starts and steadier throttle response.

• Restores proper spark across cylinders for cleaner combustion
• Helps eliminate intermittent misfires and rough idle
• Reduces long cranking times caused by weak ignition

Which vehicles and OEM numbers does this UF557 coil fit?

The BDFHYK UF557 is compatible with multiple models from Jeep, Dodge and Chrysler—always verify year, make, model and OE reference before purchase. The coil matches many common part numbers used by OEMs and aftermarket suppliers for straightforward replacement.

• Fits Jeep Patriot and Compass (2007–2017)
• Also fits Dodge Journey (2009–2020), Dodge Caliber (2007–2012), Dodge Avenger (2008–2014)
• Compatible with Chrysler 200 (2011–2014) and Chrysler Sebring (2007–2010)
• Compatible OEM numbers include UF557, UF-557, 50246, 4606824AB/AC, 52-1881 and many others

What are the build and durability features of this ignition coil?

BDFHYK constructs this coil from PBT imported from Germany and advanced PPO materials to enhance heat and corrosion resistance. The factory-installed chip mirrors original electrical characteristics to ensure correct firing patterns and longer service life when used with healthy spark plugs.

• PBT and PPO housing for heat and wear resistance
• Original-equivalent chip for consistent electrical performance
• Corrosion-resistant design to withstand engine bay conditions

How easy is installation and what maintenance helps longevity?

Installation is straightforward for anyone comfortable removing and reinstalling coil packs—this is a direct replacement designed to fit existing mounting points and connectors. To prolong coil life, maintain spark plugs and wiring; aged plugs force coils to work harder and can shorten their lifespan.

• Direct-fit design uses original mounting and connectors
• Simple swap with basic hand tools for most DIYers
• Replace spark plugs on schedule to prevent coil overwork

Who is this for: The BDFHYK UF557 coil pack is aimed at owners and technicians servicing mid-2000s to 2010s Jeep Patriot and Compass vehicles, as well as compatible Dodge and Chrysler models who need a cost-effective, OEM-matching ignition coil. It's suitable for DIY mechanics who want a reliable direct replacement and for shops that require a durable coil option backed by materials and chip compatibility to reduce common ignition-related drivability issues.
