did a search and found nothing related to this. im moving to south florida where it rains all the time in the summer. i have heard several rumors about cold air intakes not being a good idea to get for your car if you plan on driving in a lot of rain or snow because of lots of moisture being able to get into the engine through the filter under the car and up the pipe. Can anybody post your thoughts on this please? i don't have my lude yet, im picking up my 5th gen from the dealer when i get down there. it's all stock and of course the very first thing i plan on doing is putting a CAI. i really don't want to use a short ram air intake. opinions please. thanks.

 

you can get an Air By-Pass vavle which sucks the moisture out and allows the air to pass through. Otherwise you might have to much rain or moisture sucked through and could possibly hydro lock the motor. Or you can always go Short Ram and not worry about that.

 

Bad idea to get a CAI unless you love dodging puddles...the bypass only works if the filter is completely submerged in water; which is not always the case for hydrolocking your motor.

 

damn that sucks, so should i go with shortram then? is there really a noticeable difference between the two?

 

no noticeable difference between the two... imo they are all the same .."an intake is an intake."

 

The shortram will be a bit more torquey and the cold air will give you more topend. I would go with the shortram because it does rain a hell of alot down there and if it were me that wouldnt be a chance i would want to take.

 

damn cool, alright thanks for the advice guys. i was totally going to just go with the CIA anyway, but not anymore. I'll get the short ram for sure. I would like the more torquey power anyway come to think of it, so that sounds good.

 

Or you could get a 2 pc cold air and take the second piece off, making it a short ram(basically). If it rains. Well, since it rains there a lot...itd be put the other piece on when its not rainy.

 

>>in process of making my CAI into a SRI<< ... where's the dam cut-off tool...


I ****** hydro'd my motor 6 months ago, I'm still rebuilding the damn thing on weekends. bleh.

 

The one i had was just connected with a rubber hose thingey with clamps...i just took one tube off and put the filter on the end of the first.

By the way, what exactly happens in a hydro lock?

Engine blows. Mainly rods snap as they can't stand for the stress made to compress water.

 

^^ what he said. I was lucky. Only one rod bent with fingernail scratches on cylinder wall. Also a slight hairline crack on piston my friend managed to exploit and use a hammer to break piston in half. Some people have even had their rods come through their blocks, so yeah, liquid doesn't compress.

Kal is absolutely right about how the by-pass wouldn't work unless filter was completly submerged, I hadn't thought about that.

How about swiping a rain sensor from Mercedes and installing it inside of filter element? Then tie that into an electronic valve that opens underhood when moisture is detected, **** thats a good idea....MINE! all mine! buwahahaha

 

I have a 92 Accord ex and I hit a puddle 1 morning when goin to work and mine hydro-locked and a rod came threw the block. So after that happened I purchased a jdm h22a and have a short ram now. So if I were u I would go short ram.

 

go short ram or force yourself into an h22 we say that like it's a bad thing

 

if you look at where the intake sits it almost completly enclosed and protected if the splash guard stays on. I dont think you will have issues with hydro lock unless you start intentionaly trying to drown your lude or hit every puddle in FL.

 

Just to kind of clear this up for me. I have an AEM CAI with no bypass valve. i do drive when it rains. and momentarily i dont have the plastic wheel well inserts that would keep water from being thrown on the filter. how safe is this. would the suction be strong enough to ingest water even if its just thrown on to the filter rather than submerged?

 

I'd get the plastic wheel well back on before it rains, but you probably won't hydrolock it, just cause the motor to possibly suck in a little water, like a mist from a spray bottle, which is not good anyway.

As for hydrolocking, you guys seem all concerned about it. Do you intentionally drive through puddles of water that you don't know how deep they are? If you have a CAI, that sits low in the fender well, just avoid standing water on the road. If it is raining, even pouring really hard, your not going to suck up water and hydrolock your motor if it is draining off the road.

Seriously, if the road is flooded over, and you don't know how deep it is, don't drive in it!

That is really all the prevention you need.

 

^^**** happens, u think I was going 5mph and DECIDED to take it into the flooded part of highway.

It was raining, i was coming home on highway about to exit, very dark, raining pretty hard. Doing about 45-50 on a 55limit road, water in lane, car next to me on left, trees to my right, start skidding losing control, spinning, trying to not hit car next to me or the trees. I remeber water coming up over the hood and nothing else till I stopped dry side of turn off up ahead.

Now if I didn't have all that crap going on and I knew I had no choice but to hit water, I would have shut off the damn engine in time.

and hitting a pothole full of water just right is enough to mess up your engine, especially if the plastic cover isn't there. just get a short ram with a heat shield or custom box.

 

I understand your situation, I have done exactly what you describe, except it was very dark, and the 'lake' on the road looked like the road until I hit it. Only difference is it was in my POS 1980 Honda Accord, fortunately, it didn't break anything when it hydrolocked. Long story short, I pulled the plugs, watched the water stream out, drained the oil, poured the water off, poured the oil back in the motor, and off I went. Rare situation, but hey, I got lucky.

My point is you probably would have hydrolocked your motor with the stock intake, because the water was just too deep, and you hit it going so fast. Like you said, **** happens, but that has nothing to do specifically with an aftermarket CAI, and a bypass valve or short ram wouldn't have made any difference.

And I don't buy hitting a pot hole just right crap, you need to SUBMERGE the intake tube to hydrolock.

 

Go for the type-s intake.

 

I have CAI, live in FL, it pours everyday here, its not that hard to just
stay out of foot deep puddles, I have a bypass valve just in case, been through
many 'deep' puddles w/ no problems. It also gets hot as ***** here, so I figure
the CAI helps rather than short ram.
But I have heard only good things about the Type S intake.

 

My car came with an AEM CAI and the first week I had it rain like a mother here in MN. Actually it's been raining all spring and early summer long and I haven't notice a hickup at all.

Don't worry about it peeps i mean if the waters over one and a half feet you shouldn't have been there anyways. But yeah sometimes when flash flood comes you might get caught up.

 

hmmmm.

hey what is a type S intake? i did a google search and all i found was stuff about acura's and stuff.

 

Type S intake is the intake that has the "dynamic chambers." It is found on the JDM Prelude Type S and the JDM Accord Euro-R or EDM Accord Type R.

Basically, it's a normal stock intake that has a larger front collection section and helps resonate the air intake. Don't think it includes a resonator either...

It improves throttle response and gives a deep intake sound. Helps throughout the powerband.

i dunno if youve ever been here... but puddles get seriously deep.

just the other day i had it up to the middle of my door... luckily i was on a side street and no one was behind me, cuz i had to back up and go another way

if i had a CAI i woulda hydro'd it.
