NGK 51217 Spark Plug Wire Set RC-GMZ045 8mm Silicone Ignition Wires

The NGK 51217 spark plug wire set (also called ignition wires or plug wires, NGK series RC-GMZ045) carries high-voltage current from the ignition coil or distributor to each spark plug. It is built to OEM tolerances using OE-quality or better materials, so the spark stays strong and consistent.

Key Features:

• 8mm ultra-low resistance magnetic core, wire-wound ignition cable that helps suppress radio and electrical noise
• OEM-spec or better spark plug and distributor boots
• High-temperature silicone outer jacket rated to 250°C / 482°F. It resists moisture, oil, fuel and cracking from temperature extremes.
• EPDM or silicone inner insulation for strong dielectric strength
• Positive-locking, corrosion-resistant stainless steel terminal ends that hold tight and resist vibration and separation
• Numbered wires for easy cylinder identification, with color-coded coil wires for simple installation
• 180-degree spark plug end boots
