That's a good question, and I've been thinking about what they're going to do with that engine lately. The change in output is not major at all, something like a 7% increase in the torque dip, and just a couple extra ponies up top (and this is projected to ONLY be on manual cars too, which seems extra strange to me).
So the differences between the engines look to be fairly minor. I'm wondering what they're doing with the intake manifold myself. A change in runner length, diameter, plenum volume, what is it? I think I read about a change in cams. I havent seen anything about a header change, which leads me to believe the torque dip is lessened as a result of the intake manifold changes. But that's entirely theory.
One of the things I immediately notice is that the taper on the back edge of the airbox is now gone. This will make fitting oil coolers with sandwich plates much more difficult on stock airbox. Nothing else seems changed, and injection molding tooling is expensive, so why did they make this change?
The "accordion tube" for the inlet is new, but seems largely unchanged as well.
So with those two very small pieces of evidence it would lead me to believe that our intake will perform just as well on that engine, since largely it appears unchanged, same MAF sensor and everything.
But from a pure theory standpoint I think it's easy to assume that our intake will perform just as well given that it provides a solid decrease in restriction. And unless they've managed to do that somewhere in their seemingly unchanged intake system, I don't see why it would perform any differently.
So time will tell, but a decrease in restriction is a decrease in restriction, and is the reason our intake makes more power over the stock intake system. I don't anticipate it'll make more power, but I do not suspect it will be less either.
