autoexact Ignition Coil & Iridium Spark Plug Kit for 3.6L V6 — 12‑Piece Complete Direct Replacement (UF648/97390)

autoexact 12-piece ignition coil and iridium spark plug kit is a direct replacement set engineered to restore reliable ignition on 3.6L V6 Chrysler, Dodge, Jeep and Ram vehicles. This complete repair kit bundles six ignition coils and six pre-gapped iridium spark plugs so you can replace the entire ignition bank in one service. Each coil is epoxy-potted and quality-tested, and the iridium plugs use a fine-wire center electrode for consistent spark delivery. The kit replaces OEM references such as UF648 and 97390 and fits a range of 3.6L applications across Chrysler, Dodge, Jeep and Ram model years listed by the manufacturer.

How will replacing both coils and plugs at once help my vehicle?

Changing all six coils and six spark plugs together reduces the chance of a single old part causing repeat failures or misdiagnosis. When engine performance issues are caused by ignition wear, a full-bank replacement restores consistent combustion across cylinders.

• Reduces future labor and repeated part purchases by replacing matching components together
• Helps eliminate intermittent misfires from mixed-age ignition parts
• Pre-gapped plugs cut setup time during installation
• Factory-prepared dielectric grease eases connector seating and protects terminals

Which vehicles and OEM numbers is this kit compatible with?

This kit is designed for 3.6L V6 engines across specific Chrysler, Dodge, Jeep and Ram model years — always verify fitment against your VIN and OE part numbers first. The product lists many OEM cross-references so you can match against parts like UF648 and 97390.

• Common fitment: Jeep Wrangler (2012–2017), Grand Cherokee (selected years), Cherokee, Dodge Charger, Grand Caravan, Journey
• Ram 1500 model years and other Chrysler 300/Town & Country applications noted in the fitment table
• Cross-references included: UF648, 97390, 95710, 93175 and other OEM numbers for confirmation
• Fitment check recommended: confirm engine size, year, and OE part numbers before purchase

What symptoms might this kit address and what should I expect after installation?

Worn coils or plugs can contribute to rough idle, hesitation, hard starts or misfire-related codes. Replacing worn ignition parts often reduces these symptoms when they originate from coil or plug degradation.

• May resolve diagnostic trouble codes P0300–P0308 when caused by ignition components
• Can improve idle smoothness and reduce engine vibration linked to misfires
• Expected plug torque: 15–20 N·m (11.06–14.75 ft·lb); factory pre-lubricated terminals included
• Durable materials: fine-wire iridium electrodes and heat-resistant epoxy coil potting

How difficult is installation for a DIYer and what tools are recommended?

Installation is straightforward for anyone comfortable with basic engine work and a torque wrench. Replacing coils and plugs typically requires removing ignition connectors and coil bolts, then seating the new plugs to the specified torque.

• Tools suggested: ratchet, spark plug socket, torque wrench, dielectric grease (included), basic hand tools
• Recommended for mechanically inclined owners or professional technicians for tight access areas
• Follow proper torque specifications and connector seating to avoid damage
• Each coil is tested before packaging; two-year warranty and lifetime technical support are provided

Who is this for? This kit is meant for owners and technicians who need a direct OEM-style replacement for the entire ignition bank on 3.6L V6 Chrysler, Dodge, Jeep and Ram vehicles. It's suited for those correcting ignition-related drivability issues or performing preventative maintenance on the ignition system. Always verify vehicle fitment, OE references and engine size before ordering to ensure compatibility.
