NGK 51177 RC-GMZ039 Spark Plug Wire Set, Silicone Mag Core

The NGK 51177 spark plug wire set (also called ignition wire set or spark plug cables, NGK series RC-GMZ039) is a vehicle-specific replacement set. It is built to OE tolerances and carries spark from the coil or distributor to the spark plugs. Worn or cracked wires can cause misfires, rough idle and poor performance, so a fresh set helps restore ignition performance.

Key Features:

• Ultra-low resistance magnetic core, with stainless steel winding over a ferrite core, for a strong spark and excellent EMI/RFI noise suppression
• High-temperature silicone outer jacket, rated above 250°C (482°F), resists heat, moisture, oil and cracking
• Inner EPDM or silicone insulation gives excellent dielectric strength and contains high-voltage current
• Stainless steel terminals grip the cable securely for lasting connections and resistance to vibration
• Spark plug boots are glued to the cable with silicone sealer for a watertight seal
• Locking spring clip at the spark plug terminal keeps the connection secure
• Cylinder lead identification tags, where possible, make installation easier
• Blue silicone insulation, 8 mm insulation outside diameter, 90-degree spark plug end boots
• Limited lifetime warranty (see packaging for details)
