Have heard so much about F-Hose being a weak link on pre-01 samples. Would like to know it functions and what symptoms to expect when it fails. ( Seems like TBB problems are well documented on these pages but F-Hose not so) If I've overlooked old threads, pls point me to them. Thx.

You'll find a lot about the f-hose on Audiworld. The common fault is a breach like with the TBB. It too is connected to the intake, so that means a loss of pressure, so loss of power and overworked turbos...
