Silicone Vacuume Hose

[Proximity Motorsport]

Hey,

I was thinking about changing all my old black standard vacuume hoses to blue silicone... and I was told that they are not as good as factory ones because they suck shut under high boost. Kinda like the standard intake. Is this true??

I know there is no gain i just want wank to make my engine look a little flasher

i wanted to do the same i did it with a red silicone hose and yes it does suck shut, the factory one is hardened for this reason to stop it sucking shut.

they dont suck shut. under vacuum it sucks in the pressure and when it comes onto boost it pushes out air. so you would be more worried about it expanding too much but that shouldnt happen.

correct me if im wrong.
