1999 Ford Expedition Ignition Coil Boots

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.

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.

This replacement boot matches the fit and function of the original part on specified years, make and models. This boot is made from quality materials to resist damage from heat and oil saturation.

Product Features:

• Durable construction – this spark plug coil boot is made from a tough rubber material that is resistant to damage from exposure to heat and oil saturation
• Quality tested – this part has undergone extensive testing to ensure a quality fit and long service life
• Trustworthy design – backed by team of product specialists in the United States

DENSO First Time Fit COP boot sets are identical in form fit color and performance to the factory-installed boots. Every part of each COP boot set construction meets or exceeds OE/OES standards.

Product Features:

• OE design ensures a tight boot seal that protects against moisture intrusion
• High temperature resistant material provides greater protection against thermal overload
• Stainless steel internal spring with resistor to suppress RFI and deliver maximum voltage to the plug
• Engineered to the specifications used by the original vehicle manufacturer for an exact fit

NGK ultra-low resistance mag core wire sets provide outstanding performance and durability. High-temp premium silicone outer jacket and inner EPDM/silicone insulation contain high voltage currents for excellent dielectric strength. Stainless steel winding over premium ferrite magnetic core delivers ultra-low resistance, a more powerful spark and excellent EMI/RFI noise suppression. OE or better specified spark plug and distributor boots ensure the highest quality fit, performance and durability in every application. Spark plug boots are glued to NGK cable with a silicone sealer for a watertight seal. Stainless steel terminals utilizing up to 3 serrated crimps bite into cable jacket and inner insulation for the highest terminal retention strength (wherever possible). Locking C-shaped spring clip with corrosion-resistant plating ensures a secure and positive spark plug terminal connection.

Product Features:

• PERFECT FIT FOR YOUR VEHICLE: Built to OEM tolerances with OE quality or better materials
• BUILT TO LAST: Outer Jacket built to withstand temperatures greater than 250 degrees Celsius, inner insulation EPDM or silicone for best dielectric strength
• STAINLESS STEEL TERMINALS: Provide the highest possible retention to ensure positive connections through the life of the set
• CYLINDER LEAD ID: Cylinder lead identification tags where possible make installation easier
• LIMITED WARRANTY: See package for details
