NGK 58407 RC-CRX064 Spark Plug Wire Set, Blue Silicone, 7mm Ferro Mag Core

The NGK 58407 (RC-CRX064) spark plug wire set, also called an ignition wire set or plug wires, is a direct-fit replacement ignition cable set. It carries high-voltage current from the ignition coil to the spark plugs. It is built to OE-level specifications and uses a 7mm ultra-low resistance ferro magnetic core to support a strong spark and reliable engine performance.

Key Features:

• Ultra-low resistance core: Stainless steel winding over a ferrite magnetic core helps deliver a powerful spark and suppresses EMI/RFI noise.
• High-temperature silicone jacket: The blue outer jacket resists underhood temperatures up to 250°C (482°F). It also resists moisture, oil and cracking.
• Strong insulation: Fiberglass braid reinforcement over EPDM/silicone inner insulation gives high dielectric strength and cable tensile strength.
• Silicone boots: 180-degree straight silicone spark plug boots, with a silicone seal at the plug boot to keep moisture out. The set has 10 straight boots and no angled boots.
• Stainless steel terminals: Corrosion-resistant terminals grip tightly to resist vibration and separation. A locking spring clip secures the spark plug connection.
• Easy installation: Wires are numbered for cylinder identification, and coil wires are color coded.
