NGK 52017 Spark Plug Wire Set, Blue Silicone 4-Wire with Coil Lead

The NGK 52017 spark plug wire set is a specific-fit, standard replacement ignition wire set designed for select Nissan applications. This 4-wire set (including coil lead) features NGK's ultra-low resistance magnetic core construction, delivering a stronger, more consistent spark while effectively suppressing EMI and RFI interference. The stainless steel winding over a premium ferrite magnetic core minimizes resistance loss, and the high-temperature silicone outer jacket paired with EPDM/silicone inner insulation provides excellent dielectric strength and long-term durability under demanding underhood conditions.

Key Features:

• 4-wire set including coil lead
• 7.00 mm insulation outside diameter
• Blue silicone outer jacket with EPDM/silicone inner insulation for superior heat and voltage resistance
• Stainless steel wound over premium ferrite magnetic core for ultra-low resistance and EMI/RFI noise suppression
• Four straight (180°) spark plug end boots and straight (180°) distributor/coil end boot, all in black silicone
• Spark plug boots bonded to cable with silicone sealer for a watertight seal
• Stainless steel terminals with up to 3 serrated crimps for maximum terminal retention strength
• Locking C-shaped spring clip with corrosion-resistant plating for a secure spark plug terminal connection
