M2 Large Core - number of cross tubes
According the old SCC article, the newest design of the M2/ASP large intercooler has 22 cross tubes, vs. 18 for the earlier design.

However, I'm looking at a local M2 large but the number of tubes it has is 15:
It definitely looks like the large in every other way. Perhaps this is a very early model?

FWIW, I just looked at a picture of my M2 Medium, and it has 22 tubes. I think the only difference between the two is the width. 15 seems significantlt smaller.

Probably not worth the risk - pity since it is effectively new and all the ducting and clamps have never been used.

They aren't the same core. (medium vs large) At one time kevin posted that the medium was a more efficient core than the large.

And if you look at the SCC article I linked to, it clearly says that the early M2 large design had 18 cross tubes and the later has 22. The intercooler pictured has 15, which is why I am confused.
