Do you guys thing it is a bad idea to use this stuff:
McMaster-Carr
for a CAI?
Space is kind of limited under the hood with my IC routing and it would be nice to have flexible tubing. I'll probably go with the Super Flexible Gray PVC Vacuum Hose in like 2.5" ID.

 

ugliness - check
effectiveness - check

 

Oh yeah, it will be ugly. I'm just making sure it will work. Sounds like I'm good there.

 

Yeah, it's rated to withstand some pressure, so it should be just fine as a turbo intake tube.
