you can use them over unless you have a numbers matching garage/trailer queen Find a newer version they are very tough Lots of cars in Detroit run 4 lol
Hey Pascal, That air cleaner flex hose is in huge demand. Apparently Performamnce Years wants to reproduce that piece and they can't find a good used one to pattern the repop off. I think they are paying big money fro that piece. One guy said he paid close to $200 for an NOS flex hose. Go on PY Forum and read up on it.
