Hi,

I'm just curious what the intercooler piping size is on the stock Evo7 or 8?

Would increasing the size by doing custom piping job increase any power by allowing more air into the engine?

Is there any other custom modification apart from the standard off-the shelf cat-back, downpipe that one can do to make an increase in power? (I'm referring only to piping and exhaust modification, not bigger turbos, ECU, injectors, etc)

Thanks for all your inputs.
