Cable Master spark plug wires for Ford 4.0L V6 8.2MM Blue — Kevlar core, double silicone jacket

These spark plug wires are engineered specifically for SOHC 4.0L V6 applications found in Ford Explorer, Sport Trac, Ranger, Mercury Mountaineer and Mazda B4000 model years 2001–2011. They combine a Kevlar-reinforced core, nickel-wound conductor and heavy-duty silicone jacketing to deliver long life, superior heat resistance and better suppression of electrical interference for modern engine electronics.

How do these wires resist heat and wear under tough driving conditions?

The Cable Master set uses a high-tear strength double silicone jacket plus a fiberglass wire layer that together protect the internal conductor from abrasion and high temperatures. Premium silicone boots and heat-resistant insulation keep connections stable even near the exhaust or tight engine bays.

• Double silicone outer jacket with fiberglass reinforcement
• Premium silicone boots for high temperature protection
• Heat-resistant insulation on each wire and terminal

What makes the electrical performance better than stock wires?

These wires use a low-resistance nickel wire-wound (mag) conductor and a Kevlar-centered fiberglass core, yielding consistent voltage transfer and improved horsepower potential compared with aging carbon-core wires. Variable-pitch winding reduces radio frequency interference while maintaining lower overall resistance for longer service life.

• Nickel wire-wound conductor for steady voltage delivery
• Variable-pitch winding to suppress RFI for sensitive electronics
• Fiberglass/Kevlar core resists stretching and pull damage

Will these fit my vehicle and how easy is installation?

The set is vehicle-specific for SOHC 4.0L V6 engines and lists fitment for Ford Explorer, Sport Trac, Ranger, Mercury Mountaineer and Mazda B4000 from 2001 through 2011. Each wire corresponds to OE routing and common terminal styles, making a direct swap straightforward for most DIYers or technicians.

• Compatibility: Ford/Mazda 4.0L V6 (2001–2011)
• Includes OEM-style boots and terminals for direct replacement
• Designed to follow original wire lengths and routing

What kind of warranty and durability can I expect?

Cable Master backs these wires with a robust warranty and construction that focuses on longevity. The combination of heavy-duty materials, Kevlar/fiberglass core and corrosion-resistant conductors is intended to extend service life and reduce replacement frequency compared with economy sets.

• 3-year or 300,000 km warranty
• Kevlar/fiberglass core for high tensile strength
• Lower resistance than carbon-core wires for longer life

Who is this for: This spark plug wire set is aimed at owners and mechanics of Ford Explorer, Sport Trac, Ranger, Mercury Mountaineer and Mazda B4000 with the SOHC 4.0L V6 engine (2001–2011) who want a reliable, high-temperature capable replacement that offers improved RFI suppression and a longer service life than standard carbon-core wires. It's a practical choice for daily drivers, weekend vehicles and engines that operate in hot or demanding conditions and where stable ignition performance matters.
