NGK 51267 RC-GMZ029 Spark Plug Wire Set, Mag Core Silicone

The NGK 51267 (RC-GMZ029) spark plug wire set delivers reliable ignition performance as an OE-quality replacement for worn or cracked ignition wires. Also called ignition wires or spark plug cables, they carry high-voltage current from the ignition coil or distributor to each spark plug. NGK is known as The Ignition Specialist and has more than 80 years of automotive experience.

Key Features:

• 8mm ultra-low resistance magnetic core with wire-wound construction
• Spark plug and distributor boots specified to OEM standards or better
• Numbered wires for easy cylinder identification, plus color-coded coil wires for correct installation
• Positive-locking, corrosion-resistant stainless steel terminal ends resist vibration and separation
• High-temperature silicone outer jacket rated to 250°C / 482°F resists moisture, oil, fuel and cracking from temperature extremes
• Fiberglass braid reinforcement over an EPDM/silicone inner insulation gives strong dielectric properties and cable tensile strength

Replacing aging wires can help correct misfires, rough idle and hesitation caused by weak spark. The wire construction also helps suppress radio frequency interference.
