Default COBB silacone hose replacement

Anyone have the problems I'm having w/ the silacone hose that runs off of your COBB (or other I suppose) intake? I'm talking about the 3 blue (or red or whatever other color you may have) hoses.
I recently had to take my COBB off and put the stock airbox back for warranty work. Well upon going to put it back on, I noticed that two of the hoses (the ones that attatch ove the spark plugs) were pretty dark and fragile looking from the heat. So I went out and bought the same hose at a local shop. Same diameter. Upon manhandling the hoses back on their respective receptors, splitsville. The stuff was so delicate, the slightest wrong angle would create a small tear which if pushed would split up the length of the hose. Man this stuff is delicate! Quite annoying as I hunched over my engine, slowly snipping away the precious lenths of hose I needed to hook up. I finally got them all on. But to tell you the truth, I am not comfortable with those hoses. After having my COBB on only a few months after buying it, one of the connections had split as a result of heat.

So, all of that just for this... Is there a more durable alternative that someone else has used? I am assuming that as long as it is a hose ( of the same diameter) to get air form the intake into the engine, it doesn't matter what type it is. Would standard black engine hose or something of the sort do OK? Just want to be sure I'm not overlooking something important.

My hoses look the same way. They turned dark, but only the ones coming from the crankcase vents. The hose from the PCV looks fine.

I have notices that a lot of people are using the clear reinforced hose from home depot for thier oil catch cans. This hose would probably work for the CAI as well.

What about just using rubber fuel line? Any drawbacks/problems with that?

I've had no problems with my Cobb hoses and I bought my CAI on the first group buy Trey did here over 3 years ago. But I have also heard a rumour they changed hose vendors. Don't know if there is any truth to that, however. Call them up and talk to them about it. They are very customer oriented and will likely take care of you. And they are always looking for feedback, good or bad...
