The tube between the air box and the throttle body on my 94 is plastic. Only the end seals are a rubbery type material. If I decide to repair the seals on mine I will clean them well with Acetone and cover the ends of the tube with wax paper before using the Permatex.
Actually, yea... this is the way it is. The ends are a hard rubber, the middle bit is plastic. On the 1991, the two outer pieces are a hard rubber and the middle is a plastic. I think in 1992 and up they brought out a single-piece with rubber ends.
In any event, both ends attaching to the air box and throttle body are flexible rubber that should work well with Permatex Black.
