Im gonna have to go with aarong.

Seeing as the ducting isnt a pipe directly connected to intake at all, extreme angles wont retard performance. Because the intake isnt sucking from the ducting, extreme angles isnt going to come into play. It'd only effect the amount of air that is routed to the filter.

Yeah maybe the filter wont get as much cold air if you have like one thousand loops in the piping.

But it wont reduce the performance of the intake it self. Thats what i think anyway.

I've done it on my car, so has aarong..
