The MSD superconducting cable with 8.5mm is the upgrade cable. Designed from the inside out, the 8.5 millimeters offer what no other cable had, namely incredible low resistance without electronic interference! In a single superconducting cable with a length of 30.5 cm (12 inch), it has a resistance of 40 to 50 ohms! This is the lowest resistance of any twisted cable. To achieve this, we use a copper alloy conductor due to its ability to carry high voltage. The result of the low resistance level is less loss in the spark energy reaching the spark plug.
