I'm planning on putting a webber 34/36 and a header on would the coil improve things enough to be worth it? I can get one for $44 at canadian tire so I'm just curious
more juice for your spark = better combustion = more efficient runnin engine....i'd change out the plugs, plug wires, rotor cap & button at the same time.....
If your stock one is in good working order, then the difference will be minimal, but if it is worn yes it will make a difference. And as stated above new wires, rotor, cap, plugs and fuel filter will make a difference too.
