I do not know if there is a difference between the 403 and the 455 air
cleaner. But that is what I have on my 455 with a K & N air cleaner
filter. There is about paper distance between them. They do not rub
and they fit nicely. Chuck Lompoc. I use the Quadrajet
cleaner. But that is what I have on my 455 with a K & N air cleaner
