autoexact Ignition Coil & Iridium Spark Plug Kit, 12pc for 3.6L V6 — Direct-Fit Epoxy Coils & Pre-Gapped Plugs

This 12-piece autoexact ignition coil and iridium spark plug kit replaces worn units on V6 3.6L Chrysler, Dodge, Jeep and Ram models, providing a complete direct-fit ignition replacement set.

Engine ignition parts wear over time and intermittent misfires, rough idle, or an illuminated check engine light often trace back to coils and spark plugs. This kit bundles six epoxy-potted ignition coils with six factory pre-gapped iridium spark plugs matched to common OEM numbers for a straightforward overhaul of the ignition system on compatible 3.6L V6 vehicles.

Which vehicles and OE numbers does this kit fit?

This kit is engineered to fit a range of Chrysler, Dodge, Jeep and Ram models powered by the 3.6L V6. Verify year, make, model, engine and OE part number before ordering to ensure exact fitment.

• Designed for V6 3.6L engines on specified Chrysler, Dodge, Jeep and Ram models.
• Replaces common OE references such as UF648, 97390 and the listed cross-references.
• Compatible models include Wrangler (2012–2017), Grand Cherokee (select years), Charger, Grand Caravan, Town & Country, Cherokee and Ram 1500 ranges noted in the product fitment.
• Always cross-check the OE number on your vehicle against the kit’s replacement list before install.

How do the iridium plugs and epoxy coils benefit engine ignition?

Fine-wire iridium electrodes and epoxy-potted coils are selected to provide consistent spark delivery and durability under typical driving conditions. The materials improve wear resistance compared with basic plugs and offer secure coil encapsulation against vibration and moisture.

• Iridium spark plugs for stable spark and extended service life.
• Epoxy-potted coils reduce the chance of internal failure and arcing.
• Heat- and vibration-resistant designs suited to daily driving.
• Factory pre-lubricated coils with green dielectric grease for easier installation.

What symptoms might indicate it’s time to replace coils and plugs together?

Worn ignition components commonly produce drivability issues that are often picked up by diagnostics. Replacing coils and plugs at the same service interval can prevent repeated visits and ensure both components operate in concert.

• Engine misfire, rough idle or hesitation under acceleration.
• Hard starting or uneven engine vibrations at idle.
• Check engine light codes such as P0300–P0308 may indicate ignition faults.
• Replacing both components together reduces the chance of repeated work and part mismatch.

How should I install and torque these parts for a reliable result?

The kit is supplied as a direct replacement set that aligns with OE fitment dimensions and installation practices. Follow manufacturer service procedures and torque specifications when installing spark plugs and coils to avoid damage and ensure reliable operation.

• Recommended spark plug torque: 15–20 N·m (11.06–14.75 ft·lb).
• Coils are pre-lubricated with green dielectric grease to ease seating and seal quality.
• Inspect wiring harness and connectors for corrosion before installation.
• Reconnect battery and clear engine codes after replacement if applicable.

Who is this for: This kit is intended for vehicle owners, independent mechanics, and DIY enthusiasts who need a complete ignition system refresh for compatible 3.6L V6 Chrysler, Dodge, Jeep or Ram vehicles. It’s especially useful when diagnostic results point to ignition-related faults or when performing preventive maintenance to restore smooth operation. Always confirm fitment against your vehicle’s year, model, engine and OE part numbers before purchase.
