NGK 58403 Spark Plug Wire Set RC-EUX067 Silicone Ignition Wires

The NGK 58403 spark plug wire set (also called ignition wires or spark plug cables, NGK series RC-EUX067) carries high-voltage current from the ignition coil to the spark plugs. NGK is known as The Ignition Specialist and builds its wire sets to OE tolerances, so this set is a dependable replacement for worn or cracked wires.

Key Features:

• High-temperature silicone outer jacket is rated above 250°C (482°F). It resists moisture, oil, fuel and cracking from temperature extremes.
• EPDM/silicone inner insulation gives strong dielectric strength to contain high-voltage current.
• EMI/RFI noise suppression comes from NGK's low-resistance wire construction, which helps protect onboard electronics and radio reception.
• Stainless steel terminal ends are corrosion resistant. They give a positive, vibration-resistant connection at the plug and coil or distributor.
• Cylinder identification on the leads makes installation easier and helps prevent misrouting.
• Blue insulation color.

Replacing aged spark plug wires helps restore smooth idle, consistent starts and efficient combustion. It can also help clear misfires caused by wire leakage. The set is backed by NGK's limited lifetime warranty.
