NGK 52419 RC-FDX001 Spark Plug Wire Set, 7mm Blue Silicone Magnetic Core

The NGK 52419 (RC-FDX001) spark plug wire set, also called an ignition wire set or plug wire set, is a specific-fit replacement that carries high-voltage current from the ignition coil or distributor to the spark plugs. NGK has made ignition components for over 80 years and builds its wire sets to OE standards for durability and performance.

Key Features:

• 7mm ultra-low resistance magnetic (SMag) core, wire-wound design
• Blue high-temperature silicone outer jacket resists underhood temperatures up to 250°C (482°F), plus moisture, oil/petrol and cracking
• Fiberglass-reinforced braiding over EPDM/silicone inner insulation for strong dielectric strength and cable tensile strength
• Noise suppression design to reduce electrical interference
• Positive-locking, corrosion-resistant stainless steel terminal ends hold tight and resist vibration and separation
• Silicone seal at the spark plug boot
• Custom-designed terminal boots give an exact fit, not a universal one
• Numbered for easy cylinder identification, with color-coded coil wires for simple installation

Fresh, low-resistance wires help restore smooth idle and consistent spark delivery, and they suit both stock replacement and upgrade use.
