New Intake and What About Restricted Air Flow?

So last weekend I installed an AEM cold air intake on my car. Love the performance and the sound! Here are some pictures:




But here's my issue: I noticed that the compartment where the intake (filter) is located, right in front of the left wheel well, is pretty much completely enclosed with all kinds of plastic panels. I tried to take a picture to show what I mean (I bent the bottom panel out of the way here and had to use a flash since the cavity is completely dark)



It seems to me that there is a way to increase air flow to the filter to improve the effectiveness of the intake. Has anyone done anything like this? I was thinking of cutting out a portion of the flat part of the wheel well and putting in a mesh screen of some sort. (see my sketch in the picture below, the mesh would obviously need to be finer than that)




That way the intake would be unrestricted to suck all its air directly from underneath the car rather than through all the little nooks and crannies. I have the impression that most air is going into the engine compartment FIRST now, meaning it is heated up before it ever gets to the intake? Does that make sense? Thoughts please, and does anyone see a downside to my proposed solution? I realize the electrical connections of the lights have better protection now when driving in heavy rain; however it doesn't rain very much where I live so I don't see a big issue with that. Thanks,

well, i guess it wouldn't hurt but my injen intake is kinda in the same area and the coolant on my car is cooler. Before I installed it my car would run at around 194-198. Now with the CAI it runs around 183-189. both these temps I had recorded were on days that in the mid 80s

I dont think your intake has anything to do with your coolant LOL.

OP, theres plenty of air there. It wouldnt be designed if it was crap. No need to cut your plastic.

the stock intake sucks the air in from the same spot so it's probably about the same temperature. Even if it was a little cooler, that couple degrees isn't gonna cool the engine.

Yea I mean I would of thought that if you install a cold air intake, cold air goes in the engine, making the engine run cooler, and the coolant wouldn't get as hot since the engine is running cooler.

I would think that with a stock intake, being so restrictive the engine would work harder to breathe. And with the engine working harder to get that air it in turn gets hotter.

Thanks for the input guys. I'm not as concerned about the air temperature as i am about the air availability. When I start the car, especially a cold start, you can really hear the intake sucking up air, it's really loud. That's why I was concerned about the amount of air that's available. Maybe I'll test it out by bending the flap back like I did in the picture and seeing if there's any difference. Summers here can get pretty hot and under those circumstances a few degrees can make a difference. I realize the stock intake is in the same location, but then we all know the stock setup of the car does not exactly provide optimum airflow in any area. That's why we all get those expensive upgrades, n'est-ce pas? lol

Right, back on subject. I would say there may be some gain since the SS bumper doesn't look like it allows much airflow to that area.

Exactly! There is no direct airflow into that compartment. The only reasonable opening is on the engine side, behind the intercooler --> hot air.
