NGK 51238 Spark Plug Wire Set RC-GMX012 Magnetic Core Ignition Wires

The NGK 51238 spark plug wire set (also listed as RC-GMX012) is an ignition cable set built to replace worn or cracked spark plug wires. It uses a 7mm ultra-low resistance magnetic core with wire-wound construction. The spark plug and distributor boots are specified to OEM standards or better. NGK is known as The Ignition Specialist and has more than 80 years of automotive experience.

Key Features:

• 7mm ultra-low resistance magnetic core: wire-wound ignition cable that helps suppress radio frequency interference
• High-temperature silicone jacket: resists underhood temperatures up to 482°F (250°C)
• Fiberglass braid reinforcement: high-density braiding over EPDM/silicone inner insulation adds dielectric strength and cable tensile strength
• Stainless steel terminals: positive-locking and corrosion-resistant, for a tight fit and resistance to vibration and separation
• Silicone seal at the spark plug: helps keep moisture out of the connection
• Easy installation: leads are numbered for cylinder identification, and coil wires are color coded
• OE-quality boots: spark plug and distributor boots are specified to OEM standards or better

This wire set helps restore reliable spark delivery. That can reduce misfires, rough idle and surging caused by deteriorated ignition wires. NGK builds its premium ignition products to meet OE durability and performance standards.
