Air Intake

I was looking through my Summit Sport Compact and i found something called the Spiral-Flex Intake tube.
I was wondering if we could use this for our cars, i dont see why not???

here is the link for the web site.

the picture isn't very clear, but it looks like dryer ducting to me. Not to say it's a bad thing. Tubing is tubing really, as long as it is self supporting enough and doesn't collapse on itself should work fine.

don't you need to run vaccum lines into/out of the intake pipe though? .. how would you attach those to this without having a leak..?

Is it possible to use this, it looks pretty damn close???
just wondering, i think it is from an s13

So will that air intake work or not, does anyone know?????
thanks

yah, i know what you're sayin, what about the vacume lines??? Where would the maf go...?

-rs200sxthat pic's intake looks like welded metal...look at the bracket welded on by the rad...:dontknow:

The stuff in the ad looks suspiciously like stainless flex-pipe. Anything made from convoluted steel like that won't be airtight. It might create a vacuum leak on one side of you maf. It would probably be cheaper and easier to make you own from scratch. Bart sells the cone filter adapters and then all you need is a 3 inch exhaust elbow and some 2 7/8 rad hose and Voila, you now have a cold air intake. I've seen this work for ca20e's and ca18et's, and when I built mine it took a couple hours and about 25 bucks in parts (plus filter element). Oh yeah I'me pretty sure that pipe in the picture is actual metal pipe and not the stuff in the ad.

how do i hook all those vacuum lines into the exhaust pipe?
I was just wondering, because there are like 4 or 5 that hook into different spots on the intake hose, and i was also wondering if i got one of those "tornado" intake things, is it suppose to go before the MAF or after?
just wondering.

Thanks

First off those Tornado things are crap. I made the sorry mistake of buying one and it didn't do a damn thing. Second, You will either have to learn to weld or find someone who knows to do it for you. I guess you could drill a hole in the pipe and JB Weld a fitting to it but it wont be very strong. I would stick with welding.

i do not know how to weld and i also do not know how to bend a pipe except with my hands.
Is there anyone on here i could pay to make me one and send it too me???
just wondering, just an idea!!!!!!!

thanks

Not really.........it's not a "cold air intake" if the filter element is within the engine bay......you need to place the filter element outside of the engine bay to be considered a cold air intake......other wise it's just an air intake sucking in a crap load of hot air, which in reality is probably no better than using the stock box. At least with it, it has a snorkle kinda thing attached to the lid to bring in air from the outside.

I guess alittle more detail would help. If you cut a hole in your fender well the exhaust elbow turns down and the filter hangs outside your engine bay. I'll get a pic for ya.

This is for ca18et, but you could do the same with ca20, either relocate the battery and drill a hole there, or run pipe across the top of the fan shroud like the OE set-up, and drill a hole like I did.

How did you dirll a hole that big, or did you cut it?
and is it worth the effort and time, does it make a big deal and does it sound good or is it not that worth it???

thanks

Hell yes its worth the effort. Cold air is more dense ergo more oxygen per cubic foot = more power, and less detonation. I noticed a lot of difference with my turbo but I don't know how much you'll gain in a ca20e.

Yeah...it makes a HUGE difference on the CA18ET to have the filter out of the engine bay vs being in the engine bay. Especially in the summer, with electric fans. Noise wise it's louder when the air filter is clamped directly to the maf adaptor....then again I think on the turbo cars it is quiter as it doesn't resonate like on NA motors.
As far as the hole I used a 3 1/2 inch hole saw......cut a perfect circle. Then I lined the edge of the hole with that black wire loom stuff.

Metal hole cutters can be rented from the Home Depot...or at least here they can be...I assume it would be the same in the US...

Yeah......rent one if you can. They get pretty pricey the larger they get. Think I paid around $20 or more for the 3 1/2", like 5 years ago. Sad thing is I only used it that one time to make the hole for the CAI, and it's been sitting collecting dust ever since.

cool, i will have to try that sometime, when the nissan is not my only form of transportation. i am trying to get my dakota on the road, just need to fix my e-brake i should be donig that soon, now it is cold here in virginia, so it will be some time b4 i get to that.
can i just use the stock piping till i get to the MAF and then take a pipe down through a hole with a filter. because making a pipe that goes from the TB to the MAF might be out of my reach because i dont know how to weld those fittings and i dont know anyone who knows how to weld or anyone that wants to help me with that. If i dont replace that pipe, will it defeat the purpose of putting the filter outside of the engine bay????

You could box of your pod like i did. Keeps hot air out and it only sucks air thru the left front fender and grill. Also its safe from bugs, water and any other objects that the engine wouldnt like!

This pic aint the best but it gives you an idea. Bottom right of pic ;)

How do you get outside air through to the inside of the box? I don't know about yours, but on mine it's all sealed up at the front corner of the car......there's no way air will funnel through the grille to the corner....all that air goes through the rad then fan shroud....which is all hot air by that point.
Only way I can see cool air making it through is with some modification......like maybe drilling a hole like mine, and have some dryer duct or something funneling up through that hole into the closed box.
With the shielded filter on mine I've never had any water ingestion problems, and it's been about 3 years now. Now before that I had used an un-shielded cone filter, and I ran into water ingestion problems from water slinging off the tire, but none with the shielded one. As far as bugs.......if it's a decent filter....there's no bugs getting through!!

I aint saying your idea is bad keith ;-) Its just that your pod will absorb alot more dust and dirt than usual, which means you have to clean it or replace it more often than usual.

I had two cooler pipes going down the way your air filter does for my side mounted cooler. Now i have a front mounted cooler so now only one pipe is running that way now which means only one hole is being used by the cooler pipe. Huge amount of fresh air.

Neway there is a hole in the front fenders on the inside that opens up to the wheel well. I use this hole on the right side to run my oil cooler lines. Another source of fresh air.

Oh....I know, I wasn't meaning to sound like that...sorry.
My filter actually stays very clean, but it's easy enough to take off and rinse as needed.
I'm not putting down your set-up either.....I was just trying to figure it out......and just because theres a hole in the fender....doesn't mean it will dump loads of cool air through it....unless you have airflow directed to it somehow. The hole in my fender is only about 2 1/2 inches, and then there's a huge bundle of wires that go through it.....so I know there's not much air getting through it.
And with an intercooler I don't think it's as critical to get cool air to the filter as it is with a non intercooled one like mine where I need all the cool air I can get.
