NGK 51372 Spark Plug Wire Set, 8mm Silicone Magnetic Core Ignition Wires

The NGK 51372 spark plug wire set (also called an ignition wire set or plug wire set) replaces worn or aging ignition wires. It restores a reliable path for high-voltage spark from the distributor or coil to the spark plugs. NGK builds it to OE tolerances with custom-designed boots for an exact fit rather than a universal one.

Key Features:

• 8mm ultra-low resistance magnetic core: wire-wound ferrite mag core cable that suppresses radio frequency interference and delivers consistent conductivity
• High-temp silicone outer jacket: withstands underhood temperatures above 250°C (482°F) and resists moisture, oil, fuel and cracking
• EPDM/silicone inner insulation: gives strong dielectric strength to contain high voltage
• Fiberglass braid reinforcement: adds tensile strength to the cable
• Stainless steel terminals: corrosion-resistant, positive-locking ends with serrated crimps that grip the cable jacket for strong terminal retention and vibration resistance
• Silicone spark plug boots: black, 180° spark plug end boots with a silicone seal at the plug, plus black 90° coil/distributor end boots
• Easy installation: cylinder lead ID tags where possible, with color-coded coil wires
• Specifications: blue insulation, SMag core, application-specific fit, no wire separators included

NGK is known as The Ignition Specialist, with extensive OE experience worldwide. This wire set carries that quality into replacement ignition service for domestic applications.
