Vacuum Hose Kit
Trying to find this kit again, didn't save it like I should have!
I know I have seen them before, they were all pre-cut and everything. Looking for one for an S4 T2 and N/A.

Well quality silicone wont become old and brittle. Causing vacuum leaks and what not. I'm sure they do better in heat as well. Same reason we use silicone bushings, just better quality. There may be more.

generic auto parts store hose is cheap standard buna material which doesn't mix well with oil/gas but it does the job well enough in the vacuum system for most applications so long as you keep it away from oil, like the oiling jet system. most silicone does equally as poor in that situation, even the hose techniques stuff.
mazda used a PFE based hose more commonly found in evaporative/crankcase emissions systems. unfortunately it gets very brittle after a few years of heat cycles, but is far from cheap like most people would tend to think, it's more expensive than the generic hose you can buy over the counter.
the only thing that i dislike about even the good quality silicone stuff is it is easily pierced and rips at any imperfection relatively easily. i can play tug-o-war with rubber hoses with my pliers all day and not worry about it getting holes or ripping.

I picked up a bunch of silicon hose from these guys a couple years ago: http://www.stylinmotors.com/vacuumhose.html. The company name is lame, but the hose is extra thick, and the 3.5mm stuff will not pop off.

If you ask me, silicon looks cool and all... so if you are looking for what looks good, then go for it; but, if it took 20+ years for that old vac hose to become brittle and crack, then..... ask yourself if you are going to own this car 20 years from now, you get the idea.
