Has anyone used the dryer ducting style intake hose? If so where do I get something like that. I would imagine it has to be heavier duty than your average dryer ducting. Click the link for an example (seen in the red FD engine bay)

I think I found a place. Would 500degrees F max temperature be enough, or should I go for the stainless steel which is 1000 degrees F. Only prob with the stainless is it's not as flexible.

 

Any fire place co or heating cooling co should have the duct, 500 deg. is plenty good if the intake temps are that hi you have a big problem!
