Metal intercooler pipe
My truck has a Plastic Drivers side intercooler pipe. I discovered there is a metal replacement pipe for the drivers side 6C3Z6C646A. was this an update from Ford? does the metal pipe offer better flow?

I don't know the rhyme or reason behind Ford's random changing PNs for stuff or how they decide to label things, but I've worked on a 2003 6.0L that came with a metal pipe, while my '07 came with plastic, the change was somewere in 2004, maybe the '05 change to the heads. Ford first installed metal and later installed plastic, so you're installed a part from an earlier build, it wasn't something Ford or International released as an updated part. Either work.
Edit: what I'm trying to say it that it wasn't released as an update to fix a problem, it's just the way they did it the first time. There's nothing intrinsically wrong with the plastic tube. If it's broken the metal one would be a good change, if it's not then why fix something that isn't broken.

That would be the COLD side CAC tube which includes the pipe with rubber ends and new clamps, on the driver side of the engine, and installs in place of the the plastic tube for those who desire it.

6C3Z-6C646-A is an older part that was used on 2003/early 2004 trucks and comes with older style black boots and clamps.

or maybe 6C3Z-6C640-AA supersedes 6C3Z-6C646-A
"On 2004/05 trucks that exhibit the cold side hose/pipe blowing off at the intake manifold, replace the plastic tube with part #6C3Z-6C640-AA as in recall 05B29 (trucks built from 12-15-03 to 4-1-04), or repair as in TSB # 05-22-3 (trucks built from 4-1-05). Clean the intercooler and intake flange with brake parts cleaner. Seat the hose/pipe onto the intake manifold and torque the clamp to 9 ft/lbs (12 NM). Broadcast Message 1329, TSB 04-20-9, TSB 05-22-3."
