MSD 8.5 mm super-conductor wire sets are the finest in the industry and we recommend them for race or street. They offer an extremely low resistance of less than 50 ohm’s per foot, for more spark energy to your plugs. Copper alloy conductors wrapped in a series of silicone and synthetic materials make this wire an excellent choice for street-friendly suppression or competition use. Multi-angle MSD wires sets are bend-to-fit. MOROSO sets for Street/performance. Our own wire kit uses MOROSO Ultra-40 wire and is for any all-out racing application.
