Discovered this material yesterday - a buddy at cars-n-coffee had it for his 914. Perfect size and appears to mimic the early material exactly. I am waiting to hear where he sourced it from. I know Jim has some good stuff too - I have his intake set on Blumaxx. I think the inside of Jim's tubes is silver. These are heavy cardboard. Maybe the same material?
That's the correct interior (corrugated cardboard), not sure if it's some sort of moire effect from the picture taken at an angle, but is there a patterning of grayish dots on the exterior surface?
EDIT: The original tubes I've seen have a somewhat more plasticky, shiny exterior coat than I'm seeing in that 914 piece. But if it's the right diameter it looks like it would be a very good solution.

Funny...I was looking at a 914 at a car show and thought that cooling tube looked correct...but never went any further in investigation. Looking forward to seeing what you find out, Ed.
Yes, those are accurate colors. These are the real deal card board, same correct interior and look and feel to the original part. There were gray "dashes" on it in a sequential pattern, but that could be sprayed to remove and get a slightly more correct black sheen. The link to the 911 duct work is the one available now, with the silver inside lining. They look stock also when fit to the car (I have a set from Jim).
As to the switchover, it was after 1980. Here's a picture of a 1980 with the original tubes:
This is one of the original intake tubes from my newly acquired '79 parts car, the cardboard is sandwiched in between inner and outer material, fortunately for I, both tubes are in good condition.
This type of tubing can be bought at any length desired at an Eberspacher dealership (well known for heater systems for cars, mobile homes, yaughts). I bought some in the Rotterdam area (Netherlands) and it is really very cheap.

IMO the chatter around "correct" tubing isn't the challenge of finding a tube which will physically fit and look good. The challenge is finding something "period correct" which will satisfy a concourse judge.
If function were the only concern, the later 16V tubes fit all the same.

Please explain why this tubing isn't period correct.
