Section 2-7 of the manual has a description of how it improves the volumetric efficiency of the engine, how more air gets into the engine. It's a pretty neat feature on the SVX. I am thinking that it doesn't always do it's thing in the low rpm zone but hey no proof. There isn't any detail on when it opens and closes relative to throttle position. It is very interesting.

Yes it is. I can't remember all the words that "IRIS" entails (Induction Regulating ??? System -- or something like that -- I'll have to look it up). It is a highly tauted feature on the Subaru boxer engines, though.
