Motor - esc - battery wiring ? ( need help from profesional )

[Jason]

hey guys im using this wiring and connectors on my 3s , 4s traxxas 1/10 slash :

motor = 4mm bullet connectors
esc = 4mm bullet connectors , 13awg wires on deans plug
battery = 12awg wires on deans plug

if I change all this for 10awg wires all around and 6.5mm bullet connectors do I will have a noticeable difference in power/punch or it dont value the hassle to change all this ?
