There are two options with your cluctch assist parts. 1. Remove the hard line and replace with a silicone line. or 2. Get rid off it all.

Here we see the factory hard line. It is always in the way when working on the intake hoses. You can replace it with a 10mm silcone hose if you like.
Here is the new hose in place. It runs from the firewall down to the front side of the tranny to the vacuum canister in the next picture.
This shot is from the passenger wheel well. The active aero package is also removed. This hunk of metal does little more than hold vacuum to help you push the clutch pedal you girly man. :P
Here we see it from the bottom. Also sans active aero. Just 3 bolts and you are able to remove it.
Here is the line at the firewall capped off.
Good riddance to 4.3 lbs. If you have upgraded your clutch pressure plate you really won't feel any more difference in the pedal.
