PCV hose on magnum

I'm installing a magnum intake on my non magnum Neon. I've noticed that the magnum engines have a very large insulated PCV hose. Does anybody know why its insulated? Can I just use some regular hose?

Thanks

I've wondered that too. Mystery to me though, doesn't seem to be a point to it. I'm using 3/8" fuel line from the VC down to my magnum mani, but 3/8" won't go over the barb on the manifold, so I used a short section of 1/2" heater hose as a coupler. You'll only need 2 inches of the 1/2". The 3/8" hose goes into 1/2" hose about an inch, and then the other inch of 1/2" slides onto the barb. I used a hose clamp to keep that short piece of heater hose on the 3/8" fuel line. Works great, 'cept I've got to change it a bit when I install my catch can that sitting at home right now.

^^ Thanks. Anyone else know why the hose is insulated on a magnum?

It helps prevent blockage of the hose by keeping any oil that finds its way inside warm(er), so that it can more easily flow (into the intake manifold

). At least that is what I think.
