NGK 51439 RC-GMX110 Spark Plug Wire Set, 7mm Magnetic Core Ignition Wires

The NGK 51439 spark plug wire set (also listed as RC-GMX110) is an ignition wire set, also called spark plug cables, built to carry high-voltage current from the ignition coil or distributor to the spark plugs. It uses a 7mm ultra-low resistance magnetic core construction. NGK designs it to meet OE tolerances and to help prevent misfire, crossfire and radio frequency interference (RFI).

Key Features:

• 7mm wire-wound, ferrite magnetic core cable with ultra-low resistance for a strong spark
• Variable pitch winding suppresses RFI and EMI across a wide frequency range
• Silicone insulation and outer jacket for high dielectric strength and heat resistance
• OEM or better specified spark plug and distributor boots for a precise fit
• Positive-locking, corrosion-resistant stainless steel terminal ends resist vibration and separation
• Numbered leads for easy cylinder identification, with color-coded coil wires to simplify installation

NGK is a leading ignition specialist with extensive OE experience. Replacing worn or cracked plug wires with this set helps restore smooth idle, consistent performance and reliable ignition. Cross-references include 671-8072, 671-8171, 118075, 118081, 700531 and 35-8337.
