How necessary is the by-pass valve for the AEM CAI, or any CAI for that reason. I live in Northern Ohio, there is snow and rain. I don't want to hydro lock my car. But the only way that I know to hydro lock my car is to submerge the filter in a puddle of water. But does this mean that mositure and splashes of water that hit the CAI filter do not enter the engine and effect it? Sorry im very timid about getting a CAI and if something goes wrong no cash to pay for a new engine and/or repairs.
Thanks, Jon

For the intake to suck up water you basically have to go through 8-12 inches of water. Unless it floods that much in Ohio you don't really need it.

I have it on my car because I live below sealevel in Charleston, SC.

It floods everyweek.

There is a video somewhere on the internet of some guy revving his engine while his buddy sprays the filter with a hose. It does nothing. By the time a drop of water would make it to the engine... it's been vaporized and just would act like humidity in the air. If your worried about **** getting in or on the filter, get an Injen... the filter is in the bumper.

Anyone know if I can get an AEM CAI for an HX?

From what I have heard the injen has been causing most of the hydrolocking, but I could be wrong. There are 2 ways to be safe without a doubt.

A. leave the intake stock

or

B. get a sri

simple solution, dont drive through deep puddles of water.

why dont u consider a K & N FIPK II, its a powerful sri for our cars

The SRI give more low end power, and I don't want that, and it makes alot of noise when running the car below 4k rpm.
directed to civic2k1rarcer, K&N make more than just filters? i was unaware, or is that a more water resistant filter? im gonna search for it, but just really want peoples opionions before i invest the 200$ or so for the CAI and possibly another for the bypass, another thing is a local shop that sells AEM said that the bypass valves break pretty often also. Is that true.

 
Rep Power: 330

they had some recalls on an earlier version of the bypass where the inside diaphragm of the valve came off and got sucked into peoples throttle bodies. they have fixed the problem and i believe all current bpv's are safe and reliable.

So what do you think of this, get the AEM CAI w/ the bypass, if the bypass fails at any time, just drop it and use the CAI? I do believe by the DIY that i read the bypass can be removed at any time.

 
Rep Power: 412

LOL, you have to cut the pipe to install the bypass.


This is where mine ist installed.........

 
Rep Power: 330

it can be removed whenever you want. but i wouldnt waste my time/money. consider your driving habits and the area you live in, if you think its gonna be on your mind when it rains, then go with the setup. if not, it doesnt matter what kind of intake you get, its just a filter on a stick.

Acuually, the SRI gives more highend power while robbing some low end. It doesn't make noise unless you step on the pedal. Normal driving won't make noise. I think CAI is for lower-end.

actually from hearing people on this site, the k&n fipk II is pretty quiet under 4k rpm, and starts getting louder above 4k, yes k&n also makes intake systems and people say that this intake is consistent with power, meaning it delieves power throughout the entire rpm intstead off robbing lots of low end and giving high end power, i dont have this intake but will be getting it in about two weeks so ill let u know how it goes. people who have had the aem cai who switched to the fipk II have said that the fipk II is more powerful, but again thats what ive heard from one or two people on the site, ive never had either, so im not 100% sure

Not if you have a LX, there are 2 peices to the piping

i would get it just to stay on the safe side. I mean $30 for the bypass valve is better than $$$$ for a new engine.

Well I have an Injen CAI and I bout a bypass valve for it. The injen cai is a two piece so I thought that I could just put the BP vavle where it is already seperated. On the buttom piece of the intake the end of it has some sort of lip to it and the BP valve just slides right off when you try to tighten it. Some one told me to get the 2.5 size so i did. Do i have to cut that piece with the lip of and if some with what.

But the bypass won't engage until you fully submerge your filter in water. Plus I've heard it robs power. If you know it's gonna rain hard the cai easily converts to an SRI by removing the lower pipe, if you look there are pics of this being done. I've personaly driven through some pretty deep puddles and nothing has ever happened. Only it scared the F**K outta me. Last bit, the CAI made a difference I can feel, look at AEM's site, the CAI gains more HP than their SRI.

Do you not see the 2 pieces of piping? it's connected below the Valve.

No you can't just place the valve there. The lower pipe is bigger than the upper pipe.

I hear alot of people saying that the CAI's cause hydrolock alot because the filter is almost on the ground. I am not to sure if I would or wouldnt buy one either but for those of you that have them have you ever drove your car while it was raining lets say for several hours like on you way to a show or some thin like that or did you pull over? ( sorry if I seem stupid but when I went to buy a AEM yesterday the guy told me I wouldnt want one and if I got one I better watch that my motor doesnt hydrolock) I live in PA so I dont drive my car in the snow but do drive it in the rain so....................................

I live in PA and have a AEM CAI on my car. I haven't hydrolocked my car, although I do get wide-eyed when I'm driving in heavy rain, looking for any standing water so I can avoid it. As far as putting the by-pass valve in, I've heard so many different things, how it doesn't work, it could break and send a piece into your engine (using the "engine" term lightly). I haven't had a problem so far and its been through some pretty heavy rainstorms.

I've driven around in the snow. Woken up to find my car buried because of a superb plowing job care-of penndot, and never had a problem.

Don't know if this helps, but there you go.

CAI is great, but for insurance get the bypass, SRI should be fine if your in an area that might be plagued with standing water (the kind of puddles that stay on the roadway and when you drive through `em they throw up a nice fan of water). I haven't had any problems with my CAI yet and the bypass seems to work as I have accidentally found a couple of standing water puddles at night. Generally if I know it's going to rain just be aware of where puddles might be and avoid them the best you can. Again, for $30 the bypass is a worth while investment. And yes I did have to cut the pipe for install, wow, 15-30 minutes of work. No biggie there.

Don't get impounded....

Yo thanks guys I guess I am gonna have to get it then if you say it no big deal in PA I new I could count on all of you !!

Ok now that i've found out to stay away from large bodies of standing water, aka Lake Erie, I would like to know which to get. I willing to spend 300max on a CAI. I cannot find a price on the K & N FIPK II, but can on the normal FIPK (235shipped) AEM CAI (w/o bypass) 180shipped, and injen (sorry didn't look up). the K&N typhoon is nice but is 300 cheapest i found it. Any suggestions? looks like all of them give apx the same amount of hp. Let me know, the future of my car is in your hands, well not really, its infront of mine, but not right now... l8rs
