Going with ABS or PVC, the OD seemed the problem to me. I believe the ID of a "4 inch" ABS is going to be of "Nominal Pipe Size", so will depend on the schedule. A schedule 40 4" pipe should have an OD of 4.5" and wall thickness of .237". I would also say if you're going to try plastics, the ABS has a higher melting temp than PVC, and might stay more resilient/less brittle over time.
If you really want to be ghetto...you can burn your bridge with the old airbox and cut the tube section off from the rest of the top, and really de-burl it. Fits well into the 6637.
I think what you really want is a "tube" not a "pipe" with a 4" OD. The tube should be so thin the ID will be very close to 4".
