NGK 8660 Spark Plug Wire Set RC-XX89 Silicone Ignition Wires

The NGK 8660 (RC-XX89) spark plug wire set, also called an ignition wire set or spark plug cable set, carries high-voltage current from the ignition coil or distributor to the spark plugs. It is built to OE tolerances with OE-quality or better materials, so it works as a direct replacement for worn or cracked ignition wires.

Key Features:

• 7mm ultra-low resistance magnetic core with variable pitch winding, for a strong spark and effective EMI/RFI noise suppression
• High-temperature silicone outer jacket that resists moisture, oil and fuel, cracking, and underhood temperatures above 250°C (482°F)
• EPDM/silicone inner insulation with fiberglass-reinforced braiding for high dielectric strength and cable tensile strength
• Positive-locking, corrosion-resistant stainless steel terminal ends that resist vibration and separation
• Custom-designed terminal boots for an exact fit, with a silicone seal at the spark plug boot
• Numbered leads for easy cylinder identification, and color-coded coil wires for correct installation
• Blue silicone insulation, 7.00mm (0.275") outside diameter
• Backed by an NGK limited lifetime warranty (see package for details)
