I've been looking into getting my intercooler hoses replaced, my Liberty currently has the hoses with the orange liner and they feel pretty soft and flismy. I have a bit of experience in the Turbo department on the gas side and I am surprised hard piping is not more popular especially with how dirty these run with the EGR and the hoses getting lined in oil. (I know most have them disabled) But with hard aluminum or steel pipes they could be removed and rinsed out with out worrying about rubber breaking down, the samco's seem like good hoses but they are still rubber and when they go you need a brand new hoses $$$. I read one post where the hard piping was knocked because you run more of a risk of leaking with couplers because of having double the connections. But this is not an issue if properly installed. I would rather worry about replacing a 10 dollar coupler than a 100.00 hose.
So is any one running a hard intercooler piping??? I think I might try and give it a shot, this is a site I have used before to make IC piping...
