Custom-cut, high-performance plug wires with the special long spark plug boots. These are specially made in grey with black, heavy-duty spark plug boots, same color as the original plug wires. Each wire is the exact length as an original set! Our wire kit has the tight-grip neoprene nipples to insulate the coil connections to seal out the moisture. Heat-treated terminals always fit extra tight for maximum conductivity and are zinc plated to prevent corrosion. The Hi-Tech silicone boots protect the terminals from fuel, oil and intense engine heat. The wire covering is exceptionally resistant to heat temperature of 500 degrees and vibration. The rubber-like conductor over a glass core is for maximum tensile strength, 225 lb. test. The spiral core is tightly wound for protection against escaping frequencies. Perfect for any restoration project!
