NGK Spark Plug Wires, 4-cylinder Zetec (Ford, Mazda, Mercury)

NGK spark plug wire set for Ford Zetec powered cars. These plug wires are built to meet and exceed stringent OEM tolerances. They utilize a construction method known as variable pitch wire winding to create resistance to radio frequency interference. The variable pitch winding provides suppression throughout a very wide range by scrambling and breaking up the electrical waves radiated by the firing of the spark plugs. NGK wire sets provide superior firing and fuel savings, outstanding durability, excellent noise suppression, and consistent performance.

• Set includes 4 wires (Coil Lead N/R) and pack of silicone dielectric grease.
• Variable pitch winding delivers ultra-low resistance, a powerful spark and outstanding EMI/RFI noise suppression.
• Numbered for easy cylinder identification and coil wires are color coded for correct and easy installation.
• Positive-locking, corrosion-resistant stainless steel terminal ends for tight fit and maximum resistance to vibration and separation.
• High-temp (250°+ C / 482°+ F) silicone outer jacket resists moisture, oil/petrol and cracking due to temperature extremes. This silicone jacket makes these wires perfect for high heat race applications.
• Core material is aramid composite.
• Insulation outer diameter: 8mm.
• End termination type: Solid Terminal Nut.
