NGK 52348 Spark Plug Wire Set, SMag Core, 8mm Silicone Jacket

The NGK 52348 spark plug wire set (also called an ignition wire set or spark plug cable set) is a replacement set built to OE tolerances. It carries high-voltage current from the distributor and coil to the spark plugs. NGK is known as The Ignition Specialist and has decades of OE experience.

Key Features:

• SMag ferrite magnetic core: Gives low resistance for a strong spark and helps suppress EMI/RFI noise.
• Silicone outer jacket: The high-temperature jacket resists underhood heat. Outside diameter is 8 mm.
• EPDM/silicone inner insulation: Adds dielectric strength to contain high-voltage current.
• Fiberglass-reinforced braiding: Adds tensile strength to the cable.
• Stainless steel terminals: Crimped to bite into the cable jacket and insulation for strong terminal retention.
• Sealed spark plug boots: Boots are bonded to the cable with silicone sealer for a watertight seal. Application-specific boots give an exact fit.
• Locking spring clip: A corrosion-resistant clip keeps the spark plug connection secure.

This wire set restores reliable ignition performance, helping with smooth starts, steady running and good durability. Use it for routine replacement of worn, cracked or high-resistance wires.
