autoexact Ignition Coil and Iridium Spark Plug Kit for Jeep Dodge Chrysler 1.8/2.0/2.4L — 4 Coils + 4 Pre-Gapped Iridium Plugs

This all-in-one kit from autoexact combines four ignition coils with four fine-wire iridium spark plugs so you can refresh the entire ignition channel in one service. Each coil is epoxy-potted and tested for consistent performance, while the plugs arrive preset for a straightforward installation. The package targets specific model years and engines—verify your vehicle’s year, make, model, engine size, and OE part numbers before ordering to ensure fitment.

Which vehicles and engines are compatible with this kit?

This kit is built for a range of Chrysler, Dodge, and Jeep models equipped with the 1.8L, 2.0L, or 2.4L engines across specific years. Compatibility depends on the engine code and original OE numbers; applications include multiple mid-2000s through mid-2010s model years commonly using UF557-style coils.

• Common fits: Chrysler 200 (2011–2014 2.4L), Dodge Avenger (2008–2014 2.4L), Dodge Caliber (2007–2012 2.0L/2007–2011 2.4L).
• Jeep models: Compass and Patriot (2007–2017 2.0L/2.4L) and Dodge Journey (2009–2020 2.4L).
• Direct OEM replacements for UF557 / 4606824AB / 04606824AB and similar OE codes.

How does replacing coils and spark plugs together help?

Swapping coils and plugs at the same time reduces repeat labor and helps restore a uniform ignition performance across all cylinders. New coils paired with iridium plugs lower the chance of misfires due to mixed component wear and simplify diagnostics after installation.

• Includes 4 coils + 4 pre-gapped iridium spark plugs for a full-bank replacement.
• Pre-lubricated with green dielectric grease to ease installation and ensure proper sealing.
• Recommended torque for plug installation: 18.44–22.13 ft·lb (25–30 N·m).

What symptoms might this kit address?

Age or wear in ignition coils and spark plugs can produce symptoms such as rough idle, hesitation, or misfires. When those issues are caused by ignition components, replacing both parts can often clear related diagnostic trouble codes and restore smoother running.

• May reduce engine misfire, rough idle, and hesitation when ignition parts are the cause.
• Can help clear codes in the P0300–P0308 range when linked to coil or plug failure.
• Durable, heat- and vibration-resistant construction supports everyday driving demands.

Are these spark plugs interchangeable between heat ranges?

The iridium plugs in this kit match the physical specifications of common OE heat ranges for these engines, making them interchangeable where thread size and seat match. Their preset gap and 14mm tapered seat mean you can use either equivalent heat-range plug without modifying the ignition system.

• Compatible with heat range 5 (e.g., TR55GP) or heat range 6 (e.g., ITR6F13) physical specs.
• 14mm thread, tapered seat, 1.3mm preset gap—100% interchangeable where those specs apply.
• No ignition system changes required; install as direct replacements.

This kit is backed by a two-year warranty and lifetime technical support, and each coil is quality-checked before shipping to ensure consistent performance. Use the provided fitment checklist and OE numbers to confirm match before purchase.

Who is this for? DIY mechanics and professional technicians who need a direct-fit replacement ignition solution for select Jeep, Dodge, and Chrysler 1.8L, 2.0L, and 2.4L engines. Ideal when addressing ignition-related drivability complaints or when performing routine tune-up work to maintain consistent spark delivery across all cylinders.
