NGK 58004 RC-XX400 Universal Spark Plug Wire Set 4-Cylinder, Blue 7mm

The NGK 58004 universal spark plug wire set (also called an ignition wire set or spark plug cable set) is built for 4-cylinder engines. Instead of being made for one vehicle, it has cut-to-fit leads that you trim to the length your engine needs. That makes it a practical choice for vintage, custom, and older engine setups.

Key Features:

• Cut-to-fit leads: Trim each spark plug wire lead to length for a clean, custom installation.
• Boots and terminals: Straight spark plug boots and 90-degree distributor boots, with terminals and nipples.
• Stainless steel terminals: They hold the connection firmly so contact stays reliable over the life of the set.
• Silicone outer jacket: The high-temperature jacket resists underhood temperatures up to 250 degrees C.
• Dielectric strength: Inner EPDM/silicone insulation with fiberglass-reinforced braiding contains high-voltage current and adds cable tensile strength.
• Noise suppression: A variable-pitch alloy winding over a ferrite magnetic coating gives low resistance and EMI/RFI suppression.
• Watertight boot seal: The spark plug boots are glued to the cable with silicone sealer.
• Specifications: Blue jacket, 7mm outer diameter, mag (variable pitch) core.
• Installation kit: Includes a coil lead and an instruction sheet.
• Warranty: Limited lifetime warranty. See the package for details.
