The Jacobs/MSD/Taylor are all spark plug wires. None make any more power than the other and none are any better from each other. That'* why they are in the same price range. Spark plug wires and just spark plug wires, you don't gain any HP from them (only if it'* a tune up and you gain back the HP you were losing through you old wires), but you can gain throttle response since they can send a higher charge to the spark plugs rather than the stock ones. So there should not be a debate of which one is better but rather what color you want and what name you want. The cores of all these spark plug wires are made by the same manufacturer, just crimped and sized by different companies (colors too).... Everyone gets their spark plug wires core from the same people.....
