The best intake for low end is SRI. The only bad thing about this intake is that it takes in teh hot air from the engien bay. To eliminate this problem you can build a cold air box and to get even more cold air yo ucan make a short ram system.
I used to have a CAI, and then switched to a short-ram intake. The CAI had a little better top end, but not much. I run nitrous though, so who cares about 2-4 more hp. The one think I hated about the CAI is that its a pain to get to the filter, and the filter gets dirty fast. If your gonnado just bolt ons, adn do plan to race, go with a CAI. If your gonna run any kind of FI, go with a short-ram. If your strickly NA, that extra 2-4hp will come in handy if your trying to break the 180whp mark without cracking open the engine.

I also made a cold air box over a short ram intake. The result was a large improvement in torque and sound. It was cheap, but a little difficult if you aren't handy. Here are the pictures:

WOOOOW...thank you so much!
It looks great. I think I'm going to try this when I find some free time. (Lucky for me, I have some thick scrap ABS plastic in the garage)
Is the K&N filter really worth it?
Or will the cheapy filter that comes with the intake do?
I think it looks great!!!
^^ Your set up with the combination of axion68's idea (below) would be a great set up.
iono, with everyone screaming about low end, i have to ask the question.
is low end torque really that important? yes, of course it is, but is a slight loss in low end torque really that important if it's paid back up top, and more? i'm no drag racer, so launches and getting off the line at a light isn't all that important to me, but personally i think in most racing situations (track/street/strip) we're pretty much waiting for the VTEC anyway. yeah, low end torque would get you there faster, but that's 1 gear of 700-5500 rpm and 3 more of 5500+...
iono. i'm happy with my CAI. i didn't notice the Low End drop, but i did notice the high end kick. it's all kinda irrelevant since we're all talking butt dyno's anyway...i'll probably have a better opinion after i finish the bolt-ons and headwork.
Enhanced: the box made it a little quieter and got rid of the air "woosh" sound when you shut the car off.
natcc99: I tossed the generic air filter because I was worried that it wasn't filtering very well. The K&N actually makes a totally different sound than the generic! The generic is like an air sucking sound (I didn't like it) while the K&N produces that deep reverberating growl that intakes are known for.
Monk3y: A good intake will add power through the entire RPM band. When I say I noticed a massive torque increase, that also means the top end was improved as well. My tachometer needle pulls noticeably faster in 3rd gear, I was extremely impressed the first time I made a test run.
I do a lot of second gear starts away from stop signs, etc. now because of the intake.
There is only one drawback to this intake though. In comparison to a short ram, the cold air box actually limits your top speed slightly. My airbox pulls air from underneath the car, I think at 130+ mph the turbulence underneath the car starts to reduce the flow. I might remove the dryer hose to see if that helps.
edit- forgot to mention that I also wrapped the header with thermo-tec heat wrap. I never did an intake only test, so it's possible some of my gains are a result of the header wrap.

that's an interesting DIY, i tried to do something similar to a beater 'yota truck that i used to drive. i forgot to take it all off before a smog check so you can imagine what the tech at the local gas station said when he popped the hood.
i've considered going SRI+Cold Air Box, but i'm wondering if it's possible to find sturdier materials with which to construct this kind of stuff. having worked with aluminum dryer hose, i must say that it doesn't necessarily inspire confidence when i think about putting it on my car. also, have you considered insulating the plexiglass? also what is hydrolock potential like? obviously less than a CAI...i guess you can just block off the dryer hose when it's wet.
anyway, neat DIY, it's got the engineering wheels in my head turning...

Depends on how picky you are.. I am very picky so I clean it about every 5k miles. I avoid gravel roads like the plague though. You could go 10k if you wanted because K&N filters with the oil, not the cotton gauze. This is what gives it superior flow. A dry K&N filter wouldn't do a very good job and that's why I don't believe in the generic filters.
