sr intake question

[slider2828]

For fucking realz? come on... Aluminum VS rubber.... If you can get a nice bend, should be smoother therefore less disruptive airflow, but main deal is collapse during heat. Rubber heats and gets soft, air tunnel collapses causing turbulence or restrictive air. Also your stock ones has those dumb ribs for flexibility, but causes turbulence.

Secondly if aluminum, during the bends, there is smother transition from the straight areas, not so much of rubber....

Clearly the OP is the same as the person who posted this, like 4 threads away:

Its not solely for flexibility, its main function is to avoid collapse under suction. The factory went this route b/c its necessary to have a flexible connection between the motor and factory air box. Without a doubt, an aluminum, smooth I.D. pipe, would be much better than the stock rubber hose, if you're not using the factory airbox. I'm not sure what that translates to in HP numbers... probably negligible with the stock turbo.
