NGK 51125 Spark Plug Wire Set, Blue Silicone Ferrite Mag Core 7mm

The NGK 51125 spark plug wire set (also called ignition wires or spark plug cables) is an OE-fit replacement. It carries high-voltage current from the ignition coil or distributor to the spark plugs. NGK is known as The Ignition Specialist and has more than 80 years of automotive experience. This set is built to OE tolerances and meets OE standards for durability and performance.

Key Features:

• Ferrite magnetic core: Stainless steel winding over a premium ferrite mag core gives ultra-low resistance. It supports a strong spark and suppresses EMI/RFI noise.
• Silicone construction: The blue high-temperature silicone outer jacket has a 7mm outside diameter. It is rated to withstand temperatures above 250°C. The inner insulation is EPDM or silicone for strong dielectric strength.
• Stainless steel terminals: Serrated crimps bite into the cable jacket and inner insulation for high terminal retention.
• Secure plug connection: A locking C-shaped spring clip with corrosion-resistant plating keeps the spark plug terminal connected.
• Watertight boots: Spark plug boots are glued to the cable with silicone sealer. They are made to OE or better specifications for fit and durability.
• Easy installation: Cylinder lead identification tags are included where possible.
• Warranty: Limited lifetime warranty. See the package for details.

Replacing worn or cracked plug wires can help restore smooth idle, consistent ignition and dependable engine performance.
