NGK 52270 RC-FDZ078 Spark Plug Wire Set, 8mm Silicone Mag Core

The NGK 52270 (RC-FDZ078) spark plug wire set, also called an ignition wire set or spark plug cable set, is a direct-fit replacement. It is built to OE tolerances to carry high-voltage current from the ignition system to the spark plugs. NGK is known as The Ignition Specialist and has decades of OE experience.

Key Features:

• 8mm ultra-low resistance SMag core: a wire-wound magnetic core that supports strong spark delivery and EMI/RFI noise suppression
• High-temperature silicone outer jacket: withstands underhood temperatures above 250°C (482°F) and resists moisture, oil and cracking
• Blue silicone insulation: fiberglass braid reinforcement over EPDM/silicone inner insulation gives strong dielectric strength and cable tensile strength
• Stainless steel terminals: positive-locking, corrosion-resistant ends hold tight and resist vibration
• 135-degree spark plug end boots: silicone-sealed at the spark plug boot
• Cylinder lead identification: numbered leads make installation easier
• Limited lifetime warranty: see package for details
