The "Thundervolt" custom-fit (manufactured for your specific engine) 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 conductive acrylic cover. The special dual "Zimplex" silicone outer jacket 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.
