Not necessarily. As you increase the gap, the voltage needed to break down 
across it increases. This means that the voltage across every part of the 
ignition system increases, too. 

Eventually one of two things will happen. Either the high voltage will find an 
easier path to ground and arc there, or you will run into the voltage limit of 
your coil and you'll get no arc anywhere. Either way, the engine misfires and 
you lose power. 

You can even get a situation where the capacitve coupling between the wire and 
the surrounding metal parts is sufficient to soak up the voltage.
