How about the air pipe?

what about thye air hose from the cold air duct to the air cleaner on the 81 C3? Is there a ready easy replacement out ther? Dyrer pipe from lowes or somesuch....:drink:

Brake duct hose?

I think the underhood heat might be a bit much for the plastic dryer hose. If you check one of the airplane parts places, like Aircraft Spruce, they have SCAT, SKEET, CAT, and CEET hose.
It's rubber and designed for high heat.
