View Full Version : Rain in my CAI

Installed the CAI 2 weeks ago, and its been fine. The past few days it has been raining, and today I was driving back to work, doing like 40mph, and my car down shiffted violently. Then I got on the gas pretty hard and it did it again. First thing I checked was the CAI cone filter, and the dam thing is soaking wet, which is not good.

How do you all NOT get water in your CAI when it rains? Ive searched and searched and it seems no one has had this problem.

It wasnt even raining that hard today, but there were quite a few puddles on the road.

I used the civic short ram intake and followed the directions on n-body.net. So what do I do now, how do I solve this?

Thanks everyone,

Jared

Did you put the gutter guard mesh on the corners of the front bumper where the they have the two recessed things? If you did that every time that you hit a puddle than the filter would get soaked.

yea i do have the gutter guards up front...so I guess the only way around it would be to take it off?? Theres gotta be a better way...

Thanks

I am in the NYC Metro. It s POURING today and I have driven about 25 miles in rain so far. No problems at all. I never have hada discernable problem with water in the CAI.

Although my filter does get soaked. I suppose that I oil my filter a lot, maybe that helps? I would try that the oil should help deflect the water and prevent the filter from being totally soaked.

Im not sure of the name, but it came from autozone, its a high-flow ricey cone filter, the one that n-body.net has pictured in the tech section.

if your engine ingests water it is time for a new engine. Pistons can'tcompress water and to make it simple it goes boom..Get an aem bypass valve for peace of mind

I know everyone who has said they have had a problem has been using a cheaper filter. haven't heard of anyone with a k&n, or powerstack filter run into any problems. Maybe you could try swapping to one of those and see if it solves the problem. I have driven around in the rain quite a bit and have had no problems with my k&n filter.

Thats your problem, get rid of that filter, and get a K&N or Green
filter and that will help solve your problem. You should also
cover up those two holes you made in the fenderwell (those two
ressesed slits) and that should solve your problem.

And a large amount of water in your engine will kill it.

What exactly is a bypass valve, and what does it do?

Do you mean the hole I cut in the wheel well so the intake tube would be able to fit through? Whats the best way to cover the hole?

Thanks for all the help guys

when it senses loss of vacuum when the filter is submerged it will allot the sir to be sucked in from the bypass element further up in the engine.

I think they misread.. They were asking if you cut a hole in the 2 "gills" in your lower fascia, I don't think you did.

An AEM bypass valve installes on the intake pipe intermediate of the TB and filter, and if your filter were to become submerged.. It will draw air through it. I forget the law of physics but it has to do with air resistance... Under normal circumstances you will draw air from your filter, but if it stops flowing, air will come in through your bypass. Keeps you from stalling out if your filter becomes submerged. I don't think it does much if water drops are sneaking in, though.

iceman is right..if water drops are sneaking it doesn't really mattre. A few drops of water will not do anything.

Alright, first off you guys rock....thanks alot.

Which size bypass would I need? The ga is not listed on aem's website. A part number would be great.

Thanks again,

Jared

Depends on what size intake you have.

If you are having water problems.. I would do something about it first before a bypass. I drive through bad rain all the time and my filter is hella dry. You should try putting some sort of blocker in between the front of the car and the filter ( a duct tape wall works nice).

Watch4MyBu
10-16-2002, 01:17 PM
measure the size of your intake pipe and order the bypass accordingly.

alright, since i am at work, and its time to leave, this is what i did.

I took off the coupler that holds my intake tube to the tb, and sure enough, water out the ass...so I took Seths advise and taped off underneath where most of the water was coming in....

Now i have a shop vac shoved down the tube right next to the cone, hopefully sucking up most of the water within the filter. Well see what happens on the way home.

Thanks again!

Well on the way home, she was hesitating all the way....got home, checked filter, soaking wet again....

wtf

So my tape job obviously did not work...and I noticed when I pulled up to my house when I got out I saw a river of water running out from my wheelwell....wtf !!!

Tomorrow Im going to pull the wheel and duct tape a house for the filter....cuz this is bs....

So your telling me a k&n wont get wet?? I am def. gettin a k&n tomorrow, but I dont think its going to solve the problem of being wet in the rain...

cavingman
10-16-2002, 06:33 PM
It will still get wet, but K&N filters deflect water in a sense. it's oiled so the water isnt sucked inside and stays on the surface. the AEM bypass valve probobly isnt a bad idea either

iceman
10-16-2002, 06:39 PM
A bypass isn't going to do much for you. If you drive in water that high, than you will be worrying about other problems first... The bypass is really only effective when the filter is submerged.

How far down into the fender does the civic intake put the filter?
I cut a few inches off my APOC intake to bring the filter higher up
into the fenderwell. Maybe you can try taking a little bit of lenth
off that pipe to get the filter higher up like I did... and get that
new filter!!! I'm actually putting a new Green Cone Filter
on this weekend, I'll be sure to take some pics and post them.

underthegun
10-16-2002, 10:05 PM
my cone is right up against the fender...so it does sit pretty low. Good idea though, I just might try that. Ill post pics of mine too.

Later

That was going to be my suggestion. Perhaps WHERE you cut the hole to stick the tube through your fenderwell is the problem. If it is in the path of the tire throwing off water, then the water thrown off of your tire will hit the pipe and run down into your filter. You are not filling up the pipe by sucking water into the filter, but by pouring water onto the pipe and it runs down into your filter, filling it like a bowl, then your engine starves.

I'd almost recommend taking off your filter till you can move it. It's much cheaper than sucking cups of water into your engine. But you REALLY don't want to do that, only in the emergency to get home or to the auto parts store.

depends on how much water, what rpm you were at, and whether you are lucky. Water doesn't really compress like air does, so your 9.5:1 compression ratio isn't gonna like water in it. Just a lil water you are ok, but if your intake is submerged, you will probably get water locked at the least, blow a piston (or many) more likely. If you get water locked you might be able to take out your plugs and let the whole thing dry for like a week, but you probably have to take apart the block. if you blow a piston it's time to get stage 3 heads =)

From what I've read about the AEM bypass (in SCC nonetheless) I would just figure out a different way to keep your filter dry. Gathering from what I read like Ice said, the bypass isn't really good for much unless you're driving through a river. You might want to cut you're Civic tube (or whatever you're using) shorter so the filter sits higher up in the fender as close as you can get it to the engine.

You've got a ram air, right? What'd you do with the piping? Did you just leave it there? Cause some guys here put a 2.4L shield (name?) there (the part on our car under the hood with red that says ram air). It'll prevent the ram air from throwing water into the engine compartment and onto your CAI. And Get a K&N Cone.

Well, I think I found the culprit.

Today when I lifted my hood up, I saw water dripping down from the ram air slots in my hood. So I poured a glass of water in there and it ran into the engine like a faucet.

SO i took the grills out of the ram air hood and put the black plates back with without them, and it is almost airtight now.

I noticed that where my stock airbox used to be there was a puddle there. So it seems that air was coming in through the hood, landing there, and running down my intake pipe. I also saw rust already on the clamp that held the filter to the pipe.

Needless to say i ductaped the $hit outta my wheel well just to be safe.

Also just ordered the k&n filter from summit, it will be here tomorrow morning. Looks like im good to go. Thanks for all the help.

Yea i have ram air, but removed all that plastic crap, except for the peice that says ram air. I checked out where the stock intake slots are in the front facia, it seems ok to me.

I have heard of problems with the AEM bypass. One of my friend had one and it wasn't on an AEM pipe and it was just a civic cheap pipe from autozone, and it got sucked up into his engine. Also I have heard it doesn't fint pipe unless they are AEM or INjen. Thats what I have heard, I dunno though.

I have heard the exact same thing about the bypass, I have heard of it getting sucked up into the engine when it wasn't a INjen or AEM. So I woul djust try to have the filter up more in the finder well. This is why I am kinda hesitant of doing the cai, bu tI am thinking of puytting the cai piping and cone down there and have it clamped into place and then when it does rain I can just take it off and move it to the side and put the cone WAI back on.

My filter sits directly behind my foglight, so I:

Used some sheet metal to make a deflector, that shoots whatever water gets behind the foglight straight down and away from my filter. I also made a deflector behind the headlight, to keep water that leaks in that way from dripping onto the filter.

They are all the same basic design, but water really shouldnt be an issue, Ive been through some hella bad storms, even punched the gas, and the filter stays dry

Dude, get a real air filter, not some crappy paper one. K&N has oil to help trap the dust particles, and it also repels water.

Everyone who's had the cheapo filters have problems with water, I've been running my CAI w/ K&N for two years, and I haven't had a single problem.. I love to splash through 6" deep puddles as well....

what type of damage could result from water entering the engine??

When you get water in your engine, it will be bad for the time being, I got trapped in a flood a couple years back with my 96 grand am, I tried driving out of it to higher ground and I couldn't. I got stuck and my intake was submerged and the water got higher and higher with me trapped in the car, the water was about to my windows. I had to leave it and come back after the water drained. Even after I returned to my car it would not start the rest of the day but I was patient and waited. When it did start, a mass amount of steam came out of my tail pipe as well from under my hood (it was cool) I had to change the filter cause it was completly ruined. I drove that same car for a couple more years until I wrecked it (different story) I hope that never happens again but my car was fine... damn i type alot!

I also have Ram Air hood and I got the black plates on. But when I had WAI, I noticed the filter got wet when I sprayed water directly at the plates. If you have those slots open, I am sure water could go down to the CAI filter.
