Im thinking of building one according to the instructions over at teamdelsol.com, Since my Crx has the same motor has his del sol it should go good... Anyone ever tryed this one, or tryed another one? Also how important is the little tube that goes to the crank case vent? What material did you use? Thanks for any help...

 

You can build one with steel exhaust manderal bends from jegs, jc whitney or summit but it will be heavy. To build one out of aluminum bends would be expensive so it would be cheaper to buy something like a injen.

I did it and it's the best $38 bucks I ever paid for.

that rubber tube is important when you go to do the smog test.

my material is the stainless steel type. quieter then my old iceman cai without any horsepower loss.

an extra l lb won't hurt the engine here. you sound like you haven't even tried it yourself to say it would be cheaper to buy something like a injen.

DIY cai cost: $38 plus filter

Ingen cai cost: $180+

you do the math

 

I'm going to do this as well, and i was thinking of what filter did you guys use and how much was it, i'm looking at a K&N conic (spel) with a 3" opening, thanks, and sorry for highjacking your thread

 

I made one out of steel and it weighed about 10 lbs. I used a good filter $40-$50 manderal bends $30, couplers and clamps $10. so about $85 and it will be a good intake. If you make it out of aluminum the price doubles which is about the price of a good cai. If you're not interested in saving weight then make it out of steel. but it's more than 1 lb. more like 5. You have to understand that there is so much competition im the cai market that there is very little profit now. To make a diy cold intake out of the same materials would cost about the same amount as it would to buy one.

 

Yah a few pound swont kill me...They actually sell the aluminized steel at a local mienicky* shop 18 inchs for $15, and im going to call some machine shops up tomorrow to look for someone to mandrel bend it for me...
I dont really need to worry about the smog test, my uncle runs a shop and i can get my inspection from him.

 

You could get u bends for about $12-18 depending on diameter. 2 would be enough to make a cai. Then you don't have to mess with getting them bent.

 

I am in the process of making one myself, however it will cost upward of $200.

mandrel bent aluminum from http://www.burnsstainless.com

3" piping to a 2.25" transition piece(almost exactly 64mm)

also the benefit of this on my car (90-93 integra) is with the battery relocated I can make a custom CAI without a funky bend in it around where the battery used to be- therefore the air is underneath my hood for a shorter amount of time= colder air

once completed I'll post pics along with a review of the install

 

If i get U bends, will it restrict air flow in anyway? How exactly do they bend it? Im going with 2.5'' piping, plus i dont really want to wait for it to be shipped since im going to go to my uncles shop this weekend... So either ill find a shop to mandrel it.. Or meinike will bend it for me...

 

u bends are manderal

 

duh... lol, what kind of bends do they do at meinike, because the guy offered to bend it for me, but im not sure how the bends would be, and how the air flow would work out....

 

crush bend, not what you want

 

What kind of shops do U-bends, someone told me machine shops do them..But by the time i called tonight they were closed, and all the exhaust shops i called dont do them...

 

the only places I know are custom exhausts shops(big bucks) not machinists.

 

What about this idea...


Im not sure if it would work but, I can buy the Intake pipe they sell at like autozone, Coat the inside and the outside of it with ceramic paint, then connect use that, and buy a good filter.... I was even thinking of buying two of those intake pipes, painting both connecting them with pvc clamps, then trying to fit it into my engine bay... They are aluminum, and with the extra paint it might keep it real cool.. i dont know... Just an idea...

 

Bump, any thoughts on this??

I made one. But it doesnt look as "beefy" as the other real CAI's out there. the good thing about this homemade intake is that its all in parts. So when the rain season comes, u can make it a short ram intake. Then make it a cold air intake when the rain goes away. I used mine for about a year and a half and i just recenly took it off. It just didnt look right to me compared to others. So i put the stock intake back, k&n filter and modified the stock air box to an cai air box. I've noticed a small diff in performance with the modified air box, specially when its the weather is a bit cold.

 

just say NO to cold air intakes.. i made my own for my b16crx with parts from home depot.. then i hit a puddle and this happened

 

Just say YES to cold-air intakes and the bypass valve... I dropped 0.2s in the 1/4 mile from going from the stock airbox with a ghetto-rigged dryer hose connecting it to the throttlebody to an AEM cold-air intake for a CRX... sucks what happened to you though

My brother and I made a cold-air intake for his CRX. It was VERY easy. The most expensive parts were the K&N filter and the 2.5" to 3" silicone adapter piece to connect the pieces of u-bend piping to the K&N filter. It took no longer than 3 hours and we did a lot of measuring, talking, standing around, etc.

As people are saying, make SURE you buy a mandrel-bent piece. If you go to a muffler shop they'll crush-bend you some piping. 99% of those shops don't have access to a mandrel bender, which are very expensive. Crush bending severely restricts flow, which would kind of defeat the purpose of a cold-air intake.

Here's a picture of his old setup:

see I knew you wouldn't admit when you're wrong do you even think 10 lbs even make a difference? especially on a street driven car it's not like he's going all out racing here.

here my price list for my cai:

I don't know where you go your parts but it sounds like you got rip off

u-piping: $20.00

couplings: 3 at $4.00 each.

K&N filter: $30.00

Now do the MATH $32+$30= $62.00

$62 IS less then a $180+ CAI

that looks like more then a puddle to do that kind of damage. I've when through puddles before, up to 4 inches of stand water and I haven't hydrolocked yet (knock on wood) the best thing is when you KNOW it's going to rain, just take off the extention off until it stops raining. common sense.

Cost me $7.00, home depot ABS plastic piping, those are nice cuz they have pre-bent connectors and a variety of different adaptors. No mods required, just give them your measurements and assemble it like legos. Put a breather filter on your valve cover.
