BDFHYK Ignition Coil & Iridium Spark Plug Kit for Dodge/Jeep V6 — Set of 6 UF270/4504 OE Fit, Restores Starting & Throttle Respons

BDFHYK’s kit pairs six UF270 ignition coil packs with matching 4504 iridium spark plugs to restore consistent ignition for select Dodge, Jeep and Mitsubishi V6 engines.

This complete set of six coil packs and six iridium spark plugs is engineered as a direct-replacement service kit for many 2005–2008 Dodge Ram 1500, Dakota, Durango, Nitro and compatible Jeep models (Commander, Grand Cherokee, Liberty) as well as Mitsubishi Raider applications. Each coil is built with premium materials — silicon steel core, Japan-sourced rubber boots and varnished wire — while the spark plugs use iridium electrodes and high-quality ceramic to improve ignition reliability and long-term wear resistance. OE cross-references are provided so you can verify fit before purchase.

How do the ignition coils and iridium plugs improve starting and throttle response?

Replacing worn coils and spark plugs restores consistent spark timing and intensity across all cylinders, which reduces misfires and helps the engine reach optimal combustion more quickly. That typically leads to firmer cold starts and smoother acceleration from idle to highway speeds.

• Iridium electrodes provide stable spark energy and resist erosion longer than standard plugs
• High-grade coil materials reduce internal breakdown and insulation failures
• Matched coil-and-plug set lowers imbalance between cylinders for smoother throttle response

What do I need to check before installation?

Confirming fitment and inspecting the old parts before installation minimizes surprises. Match the OE numbers printed on your current coils and plugs to the cross-references listed for this BDFHYK kit, and perform basic checks on wiring harnesses and connector condition.

• Compare OE numbers: UF270 / 4504 and alternatives shown in the product listing
• Inspect coil connectors, boot condition and spark plug threads for damage
• Replace all six coils and plugs as a set for balanced performance

What materials and assembly features set these parts apart?

BDFHYK highlights premium components and manufacturing choices intended to extend life and reliability. Coils use layered materials for electrical integrity while the plugs use an iridium tip and durable ceramic body to resist wear and maintain gap stability under combustion stress.

• Coil pack construction: silicon steel core, Japan-imported rubber boots, varnished wire
• Spark plug design: iridium electrode for long-term spark stability
• Package includes an installation manual and OE reference list for verification

Who is this for: This BDFHYK coil pack and iridium spark plug set is aimed at owners and technicians working on compatible mid-2000s Dodge, Jeep, and Mitsubishi V6 vehicles who need a full six-cylinder replacement. It’s ideal when your vehicle shows multi-cylinder misfires, sluggish throttle response, rough idle, or when the coils and plugs have exceeded typical service intervals (check your owner's manual and mileage). If you want matched components designed to be direct-fit replacements with clear OE cross-references, this kit offers a practical, all-in-one refresh for ignition systems on the listed models.
