Aside from Cowtipper's note, it should help the overall breathing & smoothing the airflow into the filter area of the intake assembly. Not the best design for maximum power gains, but it will help aid in laminar flow. I know this for a fact as I did the same velocity stack on the outermost intake area of my Subaru WRX some years ago.
Thanks again Mike!

PS - Anyone know if there are any differences in the intake inlet design between the 790cc & 865cc motors? Question of the day for me anyway...
PPS - Duh. Now in "redundant question mode." Mike seems to have already covered my bases on asking this question... Oh well, I'm off to bed now.
