Nextirrer Ignition Coils & Iridium Spark Plugs Kit Pack of 8 for 4.7L V8 — Direct Fit, Reduced Misfires

Nextirrer's kit pairs eight UF270 ignition coils with eight iridium spark plugs to restore reliable ignition performance on 4.7L V8 Dodge, Ram and Jeep models.

This complete ignition set replaces worn coils and plugs in many 4.7L V8 vehicles, including Dodge Ram 1500, Durango, Dakota, and Jeep Grand Cherokee, Commander, Liberty, Aspen, Raider and related models from late 1990s through 2008 where UF270 coils fit. The kit is engineered for direct replacement — no aftermarket wiring changes required — and the iridium electrodes provide a more durable firing point than standard plugs, helping maintain steady combustion and consistent starts.

Which vehicles and years does this kit fit?

The Nextirrer UF270 coils and iridium plugs are designed to match factory-style fitment for many 4.7L V8 Chrysler applications. Always confirm fitment with your VIN or the seller’s compatibility tool before ordering.

• Compatible models: Aspen (2007), Dodge Dakota (2000–2008), Durango (2000–2008), Nitro (2007–2008).
• Ram 1500 Pickup model years: 2002–2008.
• Jeep models: Commander (2006–2008), Grand Cherokee (1999–2008), Liberty (2002–2008), Raider (2006–2008).

How do these replacement coils and plugs improve ignition reliability?

The UF270 coils are built with thermoplastic housings and silicon steel cores to better resist heat, while the iridium spark plugs use a high-melting-point electrode that maintains a consistent spark under stress. Together they reduce misfires and help the engine run more smoothly when compared to degraded factory parts.

• Thermoplastic housing improves heat resistance and service life of coils.
• Silicon steel core enhances magnetic stability for more consistent coil output.
• Iridium electrodes need lower ignition voltage and resist wear for longer service intervals.

Is installation plug-and-play or will modifications be needed?

This kit is intended as an OEM-style direct replacement so no wiring or mounting modifications are typically required. Basic hand tools and standard safety precautions are enough for an experienced DIYer or a professional installer.

• Direct bolt-in coil design matches original UF270 dimensions.
• Spark plugs come pre-gapped per common OEM specs; verify gap before installation.
• Use the vehicle compatibility feature (e.g., Amazon "Your Garage") to confirm fit before installation.

What warranty and support are provided with the Nextirrer kit?

Nextirrer offers a 12-month window for product issues, with options for refund or exchange if the parts develop faults within that period. For questions, contact their support email for assistance before or after installation.

• 12-month service period for defective-product claims.
• Customer support available by email for fitment or product questions.
• Return or exchange options depend on the reported issue and timing.

Who is this for: This eight-pack ignition coil and iridium spark plug kit is aimed at owners and technicians working on 4.7L V8 Chrysler-family vehicles listed above who want a cost-effective, OEM-style replacement. It suits DIY mechanics replacing worn coils or plugs, shops performing tune-ups, and fleet managers seeking consistent ignition performance without extensive rewiring or custom parts. Verify vehicle compatibility using your VIN or compatibility tool before purchase to ensure correct fitment.
