NGK 52301 Spark Plug Wire Set, Blue Silicone Mag Core Ignition Wires

The NGK 52301 spark plug wire set (also called ignition wires or plug leads) carries high-voltage current from the distributor or coil to each spark plug. It is built to OEM tolerances with OE-quality or better materials. That helps restore smooth idle, reliable starts and consistent ignition performance.

Key Features:

• Silicone insulation: Blue silicone insulation with a high-temperature outer jacket rated above 250°C (482°F) to handle underhood heat.
• Magnetic core construction: Stainless steel winding over a ferrite magnetic core gives low resistance and EMI/RFI noise suppression.
• 8 mm wire diameter: The insulation outside diameter is 8.0 mm.
• 135° spark plug boots: Boots are designed to fit the application and are sealed to the cable for a watertight connection.
• Stainless steel terminals: Terminals give strong retention for a positive connection over the life of the wires.
• Cylinder lead ID tags: Identification tags, where possible, make installation easier.
• Limited lifetime warranty: See the package for details.
