DOWYTA Ignition Coil Pack & Spark Plug Kit UF557 — Set of 4, Upgraded Copper Windings, Direct Fit

DOWYTA’s Set of 4 UF557 ignition coil packs and matched spark plugs is a complete replacement kit engineered to restore reliable sparks and smoother running for 2007–2016 2.0L and 2.4L Jeep Patriot/Compass, Dodge Caliber/Journey and Chrysler 200 four-cylinder engines.

This kit combines four upgraded UF557 coil packs and four high-quality spark plugs designed for direct fitment on compatible models. Each coil uses improved copper windings and a ventilated polymer housing for heat dissipation, while the spark plugs are matched for consistent gap and firing. The set is intended as a straightforward repair or preventative maintenance upgrade when existing ignition components produce misfires, rough idle, reduced fuel economy, or trigger check-engine lights.

How do these coils and plugs improve engine performance?

Upgraded coils deliver a stronger, steadier high-voltage pulse to each spark plug and the plugs provide a consistent electrode gap for reliable combustion. Together they help reduce misfires and support more complete fuel burn without altering engine tuning.

• UF557 coils with imported copper windings for stable spark energy
• Polymer housing designed for efficient heat dissipation
• Spark plugs pre-set for correct gap and reliable firing
• Direct replacement fit to avoid modification or tuning

Which vehicles and engines are these parts compatible with?

This set is manufactured to fit a range of 2007–2016 4-cylinder vehicles from Jeep, Dodge and Chrysler. Always verify your OEM part numbers or VIN fitment before purchase to ensure compatibility.

• Jeep Patriot (2007–2016) — L4 2.0L and 2.4L
• Jeep Compass (2007–2016) — L4 2.0L and 2.4L
• Dodge Caliber (2007–2012) — L4 2.0L
• Dodge Journey (2009–2017) and Chrysler 200 (2011–2014) — L4 2.4L

What should I expect during installation and maintenance?

Installation is designed to be bolt-on with no special tools beyond typical hand tools; technicians can swap each coil and spark plug in the order recommended by the manufacturer. Follow proper torque specs and a clean mounting surface to prevent damage and ensure lasting contact.

• Swap one cylinder at a time to preserve firing order and avoid cross-threading
• Use correct torque for spark plug and coil mounting (refer to vehicle manual)
• Inspect boot seals and wiring harnesses for wear before assembly
• Reset any stored engine codes after installation if present

How durable are these DOWYTA ignition coils and spark plugs?

These components are built with corrosion-resistant materials and quality copper conductors for extended life compared with low-grade replacements. The housing design helps manage heat, an important factor for longevity in four-cylinder ignition systems.

• Imported copper windings for consistent conductivity
• High-efficiency polymer housing to reduce thermal stress
• Manufactured to meet common OE fit and function standards
• Customer support and quality-assurance service from DOWYTA

Who is this for: This DOWYTA set is aimed at DIY enthusiasts, independent mechanics, and fleet owners who need a reliable coil-and-plug replacement for affected Jeep Patriot/Compass, Dodge Caliber/Journey, and Chrysler 200 four-cylinder models. It’s appropriate for routine maintenance, correcting ignition-related drivability issues, or upgrading worn components to restore fuel efficiency and smoother running.
