Stock intake
Stock intake
Hay guys I've done my own cai setup using the stock airbox. I used the stock snorkel witch goes to just above the radiator. Theres some sort of other snorkel witch goes below to the front foglights. I removed that its got a hole half the size of a someone's nail or smaller in it. It dosent seem like a snorkel can anyone tell me what it is.? I end up removing and got some flexible piping 70mm wide from the box to just were the front bumper toe bar is seems alot better flow than stock. Cheers kurt.
Pictures Guys

U cant see this pipe at all if your walking around the car.

Interesting basically you made a dual CAI intake. That box you took out was a type of resonator box, it didn't really do anything.
So how does it work? Have you taken it on the highway yet? You have to make sure that tube is very secure.
It may even work better if you disconnect the front ram air portion and seal it off, but I'm not sure. The reason being is you are pulling in are from two place, it may not be as strong as pulling it from just one.

When I said "How does it work" I was referring to your new custom intake, in other words "How do you like it?"
A CAI works best on the highway, I swapped back and forth between stock and my Nismo intake many times and came to this conclusion
1. The CAI caused me to lose a little low end off the line but was noticeably more powerful than the stock intake on the highway.
You will have to see if you can tell the difference when you floor it from 55mph.

Didn't look at your pics yet, but it's a "collector" The small whole is to let out any water/moisture sucked in from the intake at front of hood. It also holds any debris that comes it. Give it a place to fall into before the filter.

you will unlikely get any air to find it's way in and somehow "flow" up and into the intake. The high air pressure at the front will still be forced through and into the air take, hopefully not NOW be diverted down and out.
Likely the only difference now is any moisture or debris will just fall onto the road while driving or get caught in the ribs of the piping.
IF any air would flow in either direction... the ribs would slow it down.

Hmmm, I know there is a little tiny box like that on the underside of the "ram intake" that sits on the radiator, I though that was the moisture collector. I really thought it was a resonator box. I could be wrong though.
Either way NismoMax80 could be right about his other conclusions. Your going to have to open her up on the road to see if you can feel any difference.

you could absolutely be right about is being a resonator. I just don't know enough to understand how that design reduces noise. I'm sure many have removed it but haven't read experiences. It was just my hypothesis that it collected foreign matter. Sound dampening seems more likely though.
If I read the OP correctly he seemed to think the small hole was for air to enter. My thinking is for water to escape. That I'm more sure about.

Lose power? - I don't think so, I would hope that something like this would retain the "off the line" low end power of the stock intake and add the additional air at higher speeds and rpms. BUT as NismoMax80 the additional opening may be having some negative or neutralizing affect as well. Only you can tell us that.
I had to swap out my Nismo a couple times vs the stock to really figure out exactly what the difference was in my daily driving.
Have you been on the highway yet?
I gotta agree... with raz....... Either make your own CAI/SRI out of quality parts or buy a real one.
You have a really good idea going on man and it looks like you have the skill to fabricate things well, BUT... imo your using something that I don't think is going to work very well.
First off, you can't show it off, because when you tell people your using gutter/dryer hose for your CAI. No one with a true appreciation for cars is going to praise you for that. you may get a few laughs.
second, Intake stuff needs to be smooth if your trying to gain performance out of it compared to a stock setup. with all those ribs, you are going to generate a lot of turbulence in that hose. The air flow is going to be choppy and inconsistent at best which is not ideal for your your sensors. It is not where performance is gained when your trying to maximize your air flow. You want an easy, dense, smooth, uniform airflow to maximize your performance.
Last, your using something that has never been used before for this purpose. How do you know the extreme heat isn't going to compromise the hose? yeah it can take the heat from a dryer puffing out hot air, but we are talking about even higher temperatures, extreme amounts of suction and forces going through it at all times, and its open to the out door elements which will cause it to age and weaken much faster than sitting behind your dryer indoors. How do you know that in a year or two (if it lasts that long) your not going to be on a date or driving your mom around and your car shudders to a halt and you have to explain to your mom or potential woman that you replaced your air box with a gutter hose.... and that is why your both stranded on the side of the freeway wishing your renewed that AAA membership!
I am betting you spent a good chunk of change on this setup. a chunk of change that could have gotten you something like this.

This whole set up cost under 50 bucks and its made from solid stainless steel and a high quality filter. There are a few budget and DIY CAI/SRI tutorials on this site. I suggest following one of those, and trash the hose idea. Not because it wont work, but because you know the other stuff out there DOES.
peace of mind
sorry to nay say. I am all for new unique mods. But you gotta make sure the function of the mod doesn't suffer from the idea.

Agreed, the question is, does it work at all, can you feel any difference? If so then it's your prototype get some better material and optimize it, if not, no biggie buy a CAI or WAI and call it a day.

Your setup. What peace of mind does your setup have. Does it work and what proven gains does it have?
Custom eh? Nice, what I like about yours is that the MAF is close to filter, like on the stock set up. Mine is a little further away, I think that may be part of the "lag" on aftermarket intakes
yup it was real easy. I've been making custom intakes for a while now. I've bought the 300 dollar intakes and i've made intakes for 40-60 bucks, and i would bet my life, it is impossible to tell the difference in performance. They function exactly the same way, the only difference is material of the metal. I even like the sound better since my tubing is a tiny bit thicker, its not as civic like when your up in the higher RPM. I was talking to some performance guys and they told me everyone has their own opinions but they have made their own intakes for their race cars and they find that they always got better numbers on the dyno when the MAF was closer to the filter. Even if they are wrong 1-3 hp is nothing to get upset over. just it being cooler outside can adjust you 10-13 hp.
