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.
