Description
These “Thundervolt” custom-fit plug wire sets were developed and dyno-tested to deliver more power and spark energy, while producing a smoother idle and improved fuel efficiency. The Ferrite spiral-wound core is coated with an exclusive copper/nickel alloy, bonded by a conductive acrylic cover. The special dual Zimplex silicone outer jacketing protects up to 600 degrees and provides extreme durability. The 100% silicone spark plug boots feature a double-spring locking plug terminal for a positive contact.
