No. Resistance will increase with length but your fix is
insignificant. The metal spark plug connectors provide the necessary
resistance for this ignition system, not the length of the wire.
Pulling off these connections is pretty common, especially if there is
any corrosion in the cap. I've also ruined these wires pulling them off
the plugs and ripping the rubber insert when it glues itself to the
plug. I now coat the plugs with a little silicone grease.
