The japanifold offers the best flow of them all.

So japanifold is the performance alternative? Although the short length may not make much difference.

Yes. From what I've read there's also a difference in the internal runners as well as in the metallurgy to prevent that cracking.
What I don't know is what years / models the japanifold was used. I don't think it was for long before they went to the " R ".

Correct. A buddy of mine over on Swedespeed (ScottishBrick) did a lot of work on this, including flow testing both the Japanifold and R manifolds. I don't remember if he ended up posting results, but I know the Japanifold is better overall.
It was used on 2001-2004 T5 and all 2.4T P2s. 2005+ turbos and all 2.5Ts had the "R" manifold.

Why is it a Japanifold? This is a Volvo stamped part made in Japan?

Bingo.
The R manifold was made in Japan as well, but the Japanifold came first, so that's where it got the name.

@Abscate - you're a machine!

Have a turn signal bulb I can't get into the socket, may stop over tomorrow if you're in the local area. Need a hand tomorrow by chance?
