2003 Ford Focus Ignition Boots

Motorcraft Spark Plug Wires are manufactured with premium-quality materials to strict Ford Engineering standards to help maintain AND control high voltage delivery to spark plugs.

Product Features:

• Backed by Motorcraft’s Service Parts Warranty
• Designed for long life – key life durability testing (equivalent to 10 years/150,000 miles) is conducted in addition to on-vehicle durability testing.
• Optimized wire lengths help minimize part numbers while still providing proper fit.
• Wires are optimum lengths for easy installation.
• EPDM/Silicone wire jacket, spark plug AND coil / distributor insulators help protect against oil and high temperatures.
• Motorcraft ignition components help prevent false check engine lights.

Motorcraft Plug Wires are Manufactured of premium-quality materials to strict Ford Engineering standards. High-Dielectric Insulation helps maintain and control voltage delivery while reducing Radio Frequency Interference. EPDM/Silicone wire jacket, spark plug & coil/ distributor insulators help protect against oil and high temperatures. Optimized wire lengths help minimize part numbers while still providing proper fit. Designed and Tested to Stringent Ford Standards.

The MSD 8.5mm super conductor wire is the performance wire. Engineered from the inside out, the 8.5 offers everything you have ever wanted in a wire; incredibly low resistance without electronic interference. In a single 12 inch length of super conductor wire there is only 40 – 50 ohms of resistance. That is the lowest resistance of any helically wound wire. To accomplish this, we use a copper alloy conductor due to it’s great voltage carrying capabilities. The low resistance results in less loss in spark energy so more reaches the spark plug. The conductor is wound extremely tight around a special center core. So tight in fact, that there is over 40 feet of conductor wrapped into a single foot of plug wire. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective electro magnetic interference (EMI) or choke. This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. The outer sleeve that surrounds the conductor assembly is just as impressive. A proprietary blend of silicone and synthetic material produce a sleeve that is highly resistant to high heat as well as abrasion and tears. Available in universal kits and bulk lengths.
