How to Intall CAI

[Mishakol129]

I just got this cold air intake for my 91 wagon and I don't know how to install it correctly. It came with two pipes, a short one and a slightly longer one. I figure that the short one is the only one that will fit properly.

When taking off the 2 air ducts for the air cleaner, I also took off the little black box that has a wire going to it (I still don't know what it does). There was an L shaped vacuum line that I took off too.

I heard you have to cut a hole to make it a true CAI but I don't know where in the blazes they're talking about.

If there was a guide on this with pics it would be really good.



Thanks

It is pretty straight forward. If you have a CAI the filter would usually be where the battary is now (from what i have seen). Is the tube you have a short tube with 1 bend or a longer tube with 2 bends?

To hook it up the kit should come with a rubber coupling or something similar which goes onto the throttle body and the pipe. the you put the filter on the other end and hook up the vaccum lines.

These MIGHT help lol (no pics. on the explained DIY )

If the filter is anywhere under the hood it is not a CAI. The CAI on our CB7 will have the filter directly in front of the passenger wheel inside the wheel well. It is directly behind the bumper lamp. The pipe is tight going between the battery and fender to get under there and to enlarge the existing hole you will want to remove the battery tray. It is much easier than it sounds.

These are of my car and will get you good visuals:

That's really neat, but how do you cut the existing hole out? I heard from someone that a dremel would work but idk. So when I enlarge the hole (somehow), what I do then is just put the pipe in the hole and then put the filter on from underneath wheel well?

I used an air powered sheet metal saw, similar to a "jigsaw". I also slit a piece of small coolant hose and covered the rough metal edges of the hole. Correct, the pipe sticks through and you'll service the filter by pulling aside the lower part of the inner fender/splash shield.

Okay, I enlarged the hole so the pipe fits now. All I did was use some vice grips and them hammer down the metal.

I heard from someone that there is a risk of getting water sucked up in large puddles... is this true?


One last thing, am I supposed to take out everything having to do with the old stock intake, including the the intake control solenoid and the intake control diaphram?... Everything right?

[Jarrett]

Yes, it's true. Stay away from puddles.

[BRcb7tuner]

Yeah if you drive in deep enough water for it to get to the filter it will suck up water and hydrolock the motor. And when your filter is way down at the bottom of your bumper it won't take very much for it to happen.

I said large puddles. If it can't go over puddles of any size, there's no point in putting it on then.

It's called a intake bypass valve i suggest you get one.

After reading this, i'm not so sure I should use the CAI anymore,

It rains hard where I live. I think i'll just use the short curvy pipe as a short ram. Or, i'll cut the long pipe so that it doesn't go through the hole under the wheel well... I don't want to be worried about sucking up water when driving down the road.

Get the bypass valve, and you'll be fine. Or just be careful. I have a CAI (regretfully... I'd take it back if I could.) I also live in swamplands. I've come across large puddles in my car, and I avoid them. Never had a problem.

That hole you widened will probably rust. Mine did, and it is going to be a seriously expensive repair in the future for me. I wish I had just used a short ram. The benefits of a CAI aren't worth that rusty hole, IMO.
Clean it with brake cleaner, wipe it down as well as you can, and spraypaint that hole immediately. Maybe you'll avoid having a rusty butthole under your hood.

Thanks a lot. I remember you saying something about that earlier. How long did it take to rust?... I'll be sure to use some Rustoleum on it.

Your CAI must be one piece, mine is in two pieces. I'm thinking of using the curvey pipe as a short ram, wouldn't that be equal to a short ram?

This is the kind I have, http://www.ebay.com/itm/ACCORD-L4-2-...5b043e&vxp=mtr
