Do a search for "Bottle fed" and you'll find a thread with part numbers for the ones you can buy at the local auto parts stores. Not exactly what you are looking for, but a start. Sorry I can't be of more help.
Go to K&N's website and they have a filter selection chart. You can sort them by size, type, etc. Pick the one you like best and work with it. Something with a base of around 5" and overall height of 6" is close to what the Pep Boys mod uses. You can also get different inlet diameters so you can match it to your intake adapter better.
