5th Gen custom CAI/Ram air?

I have a 2K GXE base model, which means no fog lights. I was curious about possibly using the two openings in the bumper as a Ram air/CAI type setup - that is, run ducting from both openings into a Y, then into the stock air intake (where these guys have been doing their own CAI's, replacing the stock resonator)
Sound plausable? Or am I just smoking crack?

ya i might trip while going thru a puddle too or when it rains but maybe you can set up something inside the y connection to prevent water being sucked in and if you keep the stock intake on you wont have enough suction to suck up water.

It would take a lot to suck up water through the tubing that way. If the tube were say immersed in water, then it could be a problem, but the tubing is bent and any would water would have to travel all the way up the tube through the scoop, through the air box, and then reach the throttle body. But still, I would place the tubing such that it doesn not have the potential to suck up anything too bad.

Think it over, guys . . .
There are only two ways you could suck water up through the lower air inlet (OSCAI or OSCAI/ram air). The first would be if the upper air inlet was blocked. The second would be if both the lower air inlet AND the upper air inlet were submerged. In the former case, the location of the upper air inlet makes it next to impossible to block it off.
In the latter case, if the both air inlets are submerged, so are you.
Remember guys, <b>WATER IS HEAVIER THAN AIR</b>. So long as the upper air inlet is functioning properly, the engine will draw air from that inlet REGARDLESS of what's going on with the lower air inlet.
In operation, the upper air inlet acts the same as an AEM bypass valve EXCEPT that the upper air inlet is open all the time. As a result, putting an AEM bypass valve on the lower air inlet is unnecessary.
Having said that, is there an issue with the ram air conversion? I'd say the answer is yes. The concern is what would happen if sufficient foreign material entered the lower air inlet to block the air filter? The way to prevent that would be to put some kind of screen in front of the lower air inlet.

Cover the openings with chicken wire. ![gapteeth](https://maxima.org/forums/images/smilies/gapteeth.gif)
The racers on TV have the air inlet coming through the headlight. They must have figured out how to get around the water issue. Maybe they just figure they'l rebuild the engine soon anyway....

try...
a 3' fan guard to prevent foreign material from entering...
You can find this on the back of your computers. Some of you have them, some not. If not, you might find them in an IC store. Radioshack perhaps?
dunno, maybe, maybe not...

More important is the fact that by installing the OSCAI conversion, you're essentially setting up a dual air inlet system. Air, of course, will follow the path of least resistance. If you stick a fan in the lower inlet that's strong enough to push a sufficient volume of air through it to make a difference, all you'll do is blow most of the air right out the upper air inlet. Why? Because there's less resistance to the air flow through the upper air inlet than there is through the air filter. That may be offset somewhat by the vacuum that's created behind the air filter when the engine is under load, but I think you get my point.

Not a fan...
Just the fan guard
Here's a pic.
