i have the m2 intake. i thought about putting a small electric fan on the box to keep the cool air circulating instead of being trapped in the box.

 

I really don't think M2 designed their box to have flaws like that. If the air really does stagnate, then maybe it's supposed to. There have been studies (SCC engineer guy, I think) that show it beneficial to have an area of non-moving air in the intake.. Something to do with decreasing the intake temp by slowing the velocity of the air and increasing the chamber volume.... I really have no idea about that, though.

I think the M2 box is a spectacular design, and you really wouldn't see any gains from your theory. Just a big waste of time.

If you really want power go buy that electric-supercharger-inline-bilge-blower thingy that people are scamming on Ebay.
