OTO-KAUTOPARTS Ignition Coil Kit with Iridium Spark Plugs — Set of 4, Direct-Fit for Jeep/Dodge

OTO-KAUTOPARTS supplies a complete ignition kit of high-durability coil packs and double-iridium spark plugs engineered to restore reliable starts, smoother idle and consistent ignition for compatible Jeep, Dodge and Chrysler 2.0–2.4L engines.

This kit combines matched ignition coils and long-life iridium spark plugs designed as a direct-replacement set for a range of 2007–2019 compact models. Every component is built to meet or exceed factory specifications so you can swap parts quickly and return the engine to stable operation. The plugs are pre-gapped for plug-and-play installation, while the coils use reinforced housings and quality internal windings to resist heat and electrical wear.

Which vehicles and engines will this kit fit?

This kit is formulated for several four-cylinder models that use the UF557 coil and 4503 iridium plug equivalents. Confirm your exact year, engine size and OEM part numbers before ordering to ensure a correct match.

• Jeep Compass & Patriot: 2007–2016, 2.4L and 2.0L L4
• Dodge Journey: 2009–2016, 2.4L L4
• Dodge Avenger: 2008–2014 (2.4L) and 2008–2010 (2.0L)
• Chrysler 200 & Sebring: model years listed with compatible 2.4L L4 engines

How do these coils and iridium plugs improve engine performance?

Replacing worn coils and plugs restores reliable spark timing and combustion consistency, which reduces misfires, smooths idle and helps regain lost power. The double-iridium tips sustain a stable spark over a long service life, while the coil materials resist heat damage to maintain voltage delivery.

• Double-iridium electrodes provide longer service life and steady spark
• High-strength coil housings reduce risk of heat-related failure
• Improved electrical conductivity for consistent combustion
• Pre-gapped plugs for straightforward swap-out

What are the build features and part numbers I should know?

The coils feature epoxy-filled windings and reinforced engineering-plastic shells to limit thermal degradation. The kit includes parts that correspond to common OEM numbers, helping you verify fitment against dealer or repair manuals.

• Coil references include UF557 and equivalents like 5C1644, C1587/88 and 4606824AB/AC
• Spark plug reference: 4503 / PK16TT style double-iridium plugs
• All plugs come pre-set to factory gap for immediate installation
• Package example: ignition coil packs x6 and double iridium spark plugs x6

Is installation difficult and what support is provided?

Installation is typically straightforward for anyone with basic mechanical skills and common hand tools; spark plugs are pre-gapped and coils are plug-and-play replacements. If you encounter fitment questions or need help during install, the manufacturer offers a warranty and customer support for guidance.

• Plugs pre-gapped—no gap adjustment required
• Designed as direct-fit replacements for listed vehicles
• Manufacturer warranty coverage and responsive customer service
• Check vehicle confirmation details to verify fitment before purchase

Who this kit is for: Experienced DIYers and independent mechanics who maintain Jeep Compass, Patriot, Dodge Avenger, Journey or Chrysler 200/Sebring models with the listed 2.0L/2.4L engines will find this OTO-KAUTOPARTS ignition kit a cost-effective route to restore ignition reliability. It also suits fleet technicians and owners wanting longer-lasting spark plugs and robust coils that tolerate higher heat and repeated starts. Always verify OEM part numbers and model year compatibility before ordering to ensure a perfect match.
