Cable Master 8.2mm High-Performance Racing Spark Plug Wires — Blue, 2001–2011 4.0L V6 SOHC, Kevlar-Reinforced & Heat-Resistant

Cable Master 8.2mm high-performance racing spark plug wires are a heavy-duty replacement set engineered to deliver durable, low-resistance ignition for 4.0L V6 Ford Explorer, Ranger, Mazda B4000 and Mercury Mountaineer engines (2001–2011).

This complete set of blue, 8.2mm spark plug wires combines a Kevlar-reinforced fiberglass core, nickel wire-wound conductor and double-layer silicone jacketing to improve durability, heat resistance and RFI suppression without straying from factory fitment. Designed to match OEM routing and firing order for SOHC 4.0L V6 engines, the set replaces multiple part numbers (WR6096, RC-FDZ080, 1F2218140, 5U2Z12259C, 3U2Z12259C) and includes a robust warranty for long-term peace of mind.

How do these wires improve reliability under high heat?

The Cable Master set uses a high-tear-strength double silicone jacket with an inner fiberglass layer to resist cracking, melting and abrasion near the exhaust manifold and other hot zones. Heat-resistant insulation helps maintain consistent spark delivery over repeated thermal cycles.

• Double silicone jacket protects against oil, heat and abrasion
• Fiberglass wire layer adds structural integrity under stress
• Premium silicone boots maintain seal and dielectric strength at high temperatures

Will these wires affect engine performance or electronics?

These resistor-type wires use variable-pitch nickel winding to balance low electrical resistance and effective radio-frequency interference (RFI) suppression, preserving ignition energy while protecting sensitive ECU and radio systems. The design prioritizes consistent voltage delivery and reduced electrical noise.

• Low-resistance nickel wire-wound conductor for strong spark energy
• Variable-pitch winding decreases RFI without excessive resistance
• Resistor ends and quality boots prevent misfires and electrical interference

Are these wires a direct fit for my 2003 Explorer or 2007 Mountaineer?

Yes—this set is made to fit SOHC 4.0L V6 engines from 2001 through 2011 across Ford Explorer (including Sport Trac), Ranger, Mazda B4000 and Mercury Mountaineer models. Cable Master ensures correct lengths, terminal types and routing to match factory installation so you don’t need modification.

• Compatible with 2001–2011 4.0L V6 (SOHC) applications
• Replaces part numbers WR6096, RC-FDZ080 and listed OEM references
• Supplied in set format with matched wire lengths for proper routing

How long will these wires last and what warranty is included?

The combination of a Kevlar-like fiberglass core and premium silicone jacketing is built for extended service life under normal driving conditions. Cable Master backs the set with a 3-year or 300,000 km warranty, reflecting confidence in durability and manufacturing quality.

• Kevlar-family fiberglass core for high tensile strength and flex resistance
• Durable materials reduce the need for frequent replacement
• 3-year / 300,000 km warranty for added protection

Who is this for: This Cable Master 8.2mm racing spark plug wire set is aimed at owners and mechanics who need a robust, OEM-compatible ignition upgrade for 4.0L V6 Ford, Mazda and Mercury vehicles from 2001–2011. Choose this kit if you want improved thermal durability, solid RFI suppression, and straightforward bolt-in fitment for routine maintenance, performance refreshes or restoration projects.
