I'm asking this because I've seen different opinions in different threads.
I'm currently in need of new wires. some people say stock are better, others say if you're looking into modding you'll eventually need bigger wires. but if you get bigger wires you need coils.

I've read on another thread somewhere that aftermarket coils are lower quality and have less voltage output. So it seems stock coils are the way to go (which contradicts what the first guy said).

are the 10.3mm wires simply for looks? same as the msd coils?

Is my best bet going for stock wires and getting new stock coils?

could anyone shed some light on the topic please?
