NGK 51031 Spark Plug Wire Set Magnetic Core Silicone Ignition Wires

The NGK 51031 spark plug wire set (also called ignition wires or spark plug cables) delivers spark energy from the ignition system to the spark plugs. It is built to OE tolerances with OE-quality or better materials, so it works as a direct replacement for worn or cracked wires that cause misfires, rough idle and hesitation.

Key Features:

• Ultra-low resistance magnetic core: Stainless steel winding over a premium ferrite magnetic core gives a stronger spark and good EMI/RFI noise suppression.
• Variable pitch winding: The loose/tight/loose winding helps suppress radio frequency interference across a wide range.
• Heat-resistant construction: The premium silicone outer jacket withstands temperatures above 250°C. The inner EPDM or silicone insulation gives excellent dielectric strength and contains high voltage.
• OE-spec boots: Spark plug and distributor boots are glued to the cable with silicone sealer for a watertight seal.
• Stainless steel terminals: Up to 3 serrated crimps bite into the jacket and inner insulation for strong terminal retention wherever possible.
• Locking spring clip: A corrosion-resistant plated C-shaped clip secures the spark plug terminal connection.
• Cylinder lead ID tags: Where possible, the leads are identified by cylinder to make installation easier.

NGK is a leading ignition specialist with extensive OE experience. This wire set restores consistent, reliable ignition performance and durability.
