Go for it!

I've been registered over there for a while now. Theres not to many people over there, but I like that it has an arcade. Sometimes it's the only thing that gets me through work.

I had this filter on my Mirage, I liked it alot. The only problem is that it's a little harder to clean. The dirt/dust build-up is mostly at the base of the heat shield.

i just came across this, was wondering what you guys thought about it?

Si Speed, thanks for adding so much to this thread. I like the fact that the S2K, and RSX intakes use cone filters, but that's about the only thing. I just don't see how they would fit our needs, and might actually complicate the situation by giving us new problems like trying to figure out fitment issues.

I haven't looked at my stock airbox in a long time becuse it's under a bunch of crap in my storage closet, but I think using our stock box makes our design a lot easier. It's got the lower opening (the one that connects to the resinator) in case we want to run something like this: Weapon*R Racing Development...to the front bumper.

Ideally, I love Bill's idea about the cowl induction because there's a ton of air to catch there, and it's got a shorter distance to travel versus running a tube to the front bumper (even though I think this route would be the easiest solution for us). I do worry about a lot of rain water being sucked directly in through the cowl induction method, not to say the bumper method would suck up less, but I think that less water would actually reach the filter area this way.

Maybe modify the stock airbox with the "Poor Man's Icebox DIY", use bigger CRV tube to the throttle body, run the Weapon R Ram Air tube to the bumper...then all we have to do is figure out how to get a cone filter to work inside the box.

After all that, I've got a stupid newb question. Why does it have to be a cone filter?

As for this idea, the intercooler area is a high pressure area, right? Well here's my RAM idea, provided there's a conical filter and it's in a sealed box:






Of course please let me know if it's wrong etc. I just figured I took my own knowledge and what I learned in this thread and made an easy possibility I saw.

ALSO, I spoke with my father who is big into the whole automobile industry and he said there is a higher pressure point at the base of the windshield, however on the FG2 I have he said that it's not much of a higher pressure area when compared to 69 camaros etc. So That's why I went downwards with this. Also, there's no snow build up etc. with the above way I pictured.

Exactly what I was thinking by saying that it would be like the j's racing one. Good job. I don't think the crv tube fits with the stock airbox though, so we would have to figure out a different sealed box for that. Thanks for the illustration.

I was looking for the Gruppe M intake for the FD2, and saw that the piece that has the hole for the cowl induction comes with the kit. Not that it makes any of it more cost effective

In a really old thread I made when I did my own X intake right before X debuted and started selling it, I used an S2K filter in place of the A'PEXi but I never got the box. I honestly doubt I have it, but I'm down to get a box and see what I can do with it. I have a video camera and I could message you what I've come up with and go back and forth etc. Btw where do you live? Other than infiniti and beyond lol

Dan, I live in the frozen wasteland of Minnesota. Getting an airbox and beginning to analyze it is the first step. I know there have been a number of people with similar ideas. Great minds think alike as they say. Anyway, the best way for us to advance is to propose ideas, especially photographs or drawings, so that we can visualize things better.

Ketch, do us a favor. Can you take a tape measurer and get the length and height of the S2000 airbox? Also, do you know how big the cone filter is and how it would compare to say, an Apexi?

props if you do it though

The cowl on the STI and the LGT are to cool the TMIC, not to bring cool air in to the intake.

[Zeuceone]

is it me or is the gruppe m intake have the scoop facing the way x does..?

The K&N is a partial solution at best. First of all, the filter area needs to be totally enclosed. Secondly, there is a provision for the factory cold air tubing, but the area where the air is drawn in is a relatively low pressure area.

On an 8th Gen Civic, we are looking at either the cowl area or the lower bumper intake area, both high pressure zones. By using tubing/ductwork, there would be a connection to the sealed airbox. A sealed airbox is critical in using vacuum to help suck in more cold air.

Lastly, I think we want to stay away from aluminum tubing. Something akin to what X is using or some homemade systems others have used with silicone tubing is the best bet. We want to keep temperatures down in the intake tract.

Thanks for offering up a possibility. Keep throwing ideas out. When we brainstorm, great ideas come forth.

Matt, since you have a stock box sitting around, can that baby be hogged out and have some type of conical filter put in there? Ideally, using the Si box would eliminate any fitment issues as it is designed for our engine bays.

[20civic07]

there really is no point changing into a crv tube. it may be wider, but the engine will suck in as much air as the throttle body opening allows. people always think that bigger is better. but if there is a restriction the bigger part is just a waste of money. as for the ractive heat shield. what does it do? think about it. it cases the cone, allowing for heat to absorb on the cone, while it may not be that much, it certainly is more than none. the engine bay is a heated environment, meaning most places in the bay will be roughly the same temp, there is still an opening for air to get in, so warm air will go through the opening from the engine bay. for the OP, that is a pretty good idea. the k&n intake i see utilizes the bottom half of the intake box. that wont do anything. find where the stock intake box goes and it goes into the fender. If there is no suction from the tube, then the bottom half of the stock airbox is useless. the intake will still be sucking in from the same place, the engine bay and there is no flow from the fender to the engine bay from the original stock air box.

Not that I can see. Give me a couple of minutes and I'll post up some pics of it.

Matt, taking a look at this setup, it looks nice and compact. I like the duct that could be used. It seems that the filter element sits partially in the duct, with a base piece that would enshroud it. This setup could make an install a lot easier, especially to the cowl area.

[mattsbobo]

Top Piece of intake box:

Bottom half of box:

Side view of top piece:


Sorry they're not the best pics. First, there's no way to connect the cone filter to the hole that leads to the MAF. Second, you would have to cut out part of the top of the box to make room for the cone filter, then fab up something for the top of the box to enclose the filter, and have the box be sealed again.

Does any of that run on sentence make sense?

I just emailed this company to see if they could help us out and make something for our car. I'll keep everyone posted on what they say. I told them that it needs to be something like the icebox was. They make carbon fiber intake systems btw.

I agree using stock box is better, but my mistake in not specifying is that I posted that up for info, but I figured the s2k cone filter can fit INSIDE the Si box when gutted out like I have mine. As for the Cowl Induction, I agree it is the best way, but as you said water is a big priority and don't forget gravity, with the cowl induction the water can go down into the intake, with the bumper intercooler area it's less likely to get up into the filter area as you said which is gravity doing it's part.
My stock airbox is the Poor Man's Ice Box, so all I need is an s2k filter to see if it fits in, which I think it should. As for the question, it's not newb, my understanding is that conical filters have more of a volume of air to suck in as a higher rate. A'PEXi uses an interior cone design with helps air flow straight and not bounce around.

Thanks for the compliment! The CRV tube does infact fit with the stock airbox. I'm having one shipped to my house, should be here in a few days. I'll have many pictures etc. in a couple days.

Right, btw I hope you feel better I just read that you're really sick. As for the airbox, I'm going to play around with the
