NGK 57403 Spark Plug Wire Set RC-VWC020 7mm Copper Core Silicone

The NGK 57403 spark plug wire set (also listed as RC-VWC020) is an OE-style replacement ignition wire set. It carries high-voltage current from the distributor or coil to the spark plugs. Worn or cracked plug wires can cause misfires, rough idle and hesitation, so replacing them helps restore smooth engine performance.

Key Features:

• 7mm, 29 gauge galvanized copper core ignition cable
• OEM-specified spark plug and distributor resistor boots
• High-temperature silicone outer jacket resists moisture, oil and fuel, and cracking from temperature extremes. It is rated to 250°C / 482°F or more.
• Premium fiberglass braid reinforcement over an EPDM/silicone inner insulation layer for strong dielectric properties and cable tensile strength
• Positive-locking, corrosion-resistant stainless steel terminal ends hold tight and resist vibration
• Wires are numbered for easy cylinder identification, and coil wires are color coded for simple installation
