Don't buy aluminum. You want some flex in the piping, get a silicone hose of the proper size/length, and the corresponding band-clamps.

i said that assuming this person was going to keep the smooth bellow or whatever they have in place. if they replace it with one piece running from lid to TB, then yea it needs to flex a little. but if they have a smooth bellow that is soft and has flex to it, the place replacing the MAF can be stiff has hell.

I know, i was just being a jackass haha. If he is replacing the MAF the best thing to do is to just get one piece that goes the whole way to the throttlebody to help eliminate any flow restrictions. I just used a single silicon hose, and it worked perfect.

The one that Doc posted would probably be your best choice! Thats nice!
