NPAUTO Ignition Coil Pack for V6 4.0L Ford Explorer, Ranger & Mustang (1991–2007) OE-style Tested

NPAUTO ignition coil pack designed to replace worn or damaged coils on 4.0L V6 Ford and compatible Mazda/Mercury vehicles from 1991–2007, restoring reliable spark and drivability.

If your V6 4.0L Ford or compatible Mazda/Mercury vehicle is experiencing rough idle, loss of power, or misfires, a failing coil pack is a common cause. This aftermarket NPAUTO coil pack is manufactured to meet OE-style electrical and mechanical specifications and covers a broad list of fitments including Ford Explorer, Ranger, Mustang, Mercury Mountaineer, and Mazda B3000/B4000 model years shown. It includes multiple interchange numbers for cross-reference, and the housing and windings are quality-tested to improve longevity and performance.

Which vehicles and model years will this coil pack fit?

This coil pack is built for many V6 4.0L Ford applications and select Mazda/Mercury models. Check engine and year compatibility carefully before purchase to ensure correct fit and connector layout.

• Ford 4.0L V6: Explorer (1991–2010 scope coverage), Explorer Sport Trac (2001–2007).
• Ford Ranger and Mustang model ranges listed include late-90s to mid-2000s where applicable.
• Mazda B3000/B4000 and Mercury Mountaineer fitments across specified years noted in interchange list.

How does replacing the coil pack improve vehicle performance?

A new coil pack restores consistent high-voltage delivery to spark plugs, which helps the engine fire evenly and efficiently. That leads to smoother idling, improved throttle response, and better fuel burn when compared with a failing coil pack.

• Reduces engine misfires and associated check-engine lights.
• Improves throttle response and reduces hesitation under load.
• Can help recover lost fuel economy caused by incomplete combustion.

What quality and interchange assurances does this part include?

NPAUTO provides this coil pack with a list of cross-reference part numbers to simplify matching: FD-480, DG452/DG455/DG459, DGE446, and common OEM codes. Materials and internal windings are tested for reliable electrical characteristics and mechanical fit.

• Multiple interchange numbers help confirm correct replacement part.
• Quality-tested housing and coils to resist heat and vibration.
• Designed to meet OE fit and connector geometry for straightforward installation.

How do I install the coil pack and what should I watch for?

Installation is typically a direct swap using the factory mounting points and electrical connector; basic hand tools are usually sufficient. Observe safety precautions: disconnect the battery, note spark plug wire or coil-on-plug order if applicable, and torque fasteners to factory specs.

• Disconnect the negative battery cable before starting work.
• Replace one coil at a time to preserve firing order if needed.
• Inspect spark plug condition and wiring harness for related faults.

Who this is for: This coil pack is aimed at DIY mechanics, independent technicians, and vehicle owners maintaining late-1990s to mid-2000s Ford V6 4.0L applications or compatible Mazda and Mercury trucks/SUVs. Choose this NPAUTO unit when you need a cost-effective, quality-tested replacement that cross-references common OE and aftermarket part numbers and when symptoms point to a failing ignition coil pack rather than other ignition components. Always confirm exact fitment with your vehicle’s VIN or factory part number before ordering.
