I was just digging around under the hood and checking out the two ducts forcing air into the IC when I noticed that there appears to be a stream of air directed into the battery box. Why so? Anyone got any insight to this?

It's not really pressurized. It's just to blow cool air into your battery since Mazda pretty much sealed it completely with that battery cover.

Yeah, "pressurized" might be a bit of an overstatement, but that same ram air that's pushing air into the IC, pushed air into the battery box as well.

Also don't forget that there is a turbo under the hood as well.... Excessive heat kills batteries.

I'm sure it's also to remove any acidic gases that escape from the battery itself. That way it doesn't build up in the box and end up corroding it in time.

Speaking of battery.....I haven't looked but these batteries are maintenance free right? Just wondering all the pictures of the battery in the manual show otherwise. I was just assuming it was a misprint.

Speaking of batteries... I have a brand-new Optima red-top battery that I would like to put in my brand-new MS3 (I pick it up tomorrow). Will the dealership give me grief over this? Sorry for the dumb question, but I've been leasing cars since 1993 and this is the first new car I've purchased since then. I bought the Optima for my Porsche 911, but I changed my mind and bought an Odyssey 680MLT (13 lbs!) to put in the 911, so the Optima is an orphan... Thanks!

So what your saying is every month I need to add distilled water if necessary?

Wrong.
You cannot buy a battery anymore that requires mtc. After a few lawsuits from people doing stupid things like putting the battery under a sink faucet, the mfrs smartened up and removed the caps.
DISCLAIMER: I have yet to see the battery in my speed--if I see it has caps on it, the damn thing is coming out a half hour later.

Wrong again!
Motorcycles still use them, next time you are at a dealer ask the guy behind the counter why he has to add acid when you buy a battery? And what those little yellow plastic caps are for.

The MS3 does have a maintainable battery (at least mine does, I looked before I posted).  Which is good because it will last longer if properly maintained.  Unless you are one of the stupid people who are going to put it under the faucet, this is a good thing.  People who are stupid shouldn't sue people because of their own stupidity. 

And if what you said were true, the manufacturers didn't 'smarten up', they 'dumbed down' their product.

I noticed that the battery box is sharing some of the air going to the TMIC so I took the lid off the battery box (and just let it breath on its own), took off the plastic snorkel that runs between the battery lid and IC shroud, and then blocked the air outlet with silver tape. Now all the cool air will go to the IC..........may not be much but it sure cant hurt (especially in the summer heat).

the main reason way that little snorkle is there is because sense mazda sealed the battery to presumably protect it from the heat of the exhaust/ turbo, they had to include some way to flush or at least dilute the hydrogen produced from the battery while iits being charged. if they didnt do this it would lead to a very far and remote chance that the hydrogen could ignite and take well... the atter with it thats about it.
