Warning To Those With Cai

[4mynikka]

I'll be installing my CAI as soon as the exams are over and I was discussing with a mechanic buddy on mine with regards to the pros and cons of having one.

PROS: we all know

CONS:
1) the much disputed HYDROLOCKING, which by the way still happens in the winter with SLUSH.... He seen it happen several times and obviously with flooding.

2) THROTTLE BODY FREEZING OPEN. I questioned him about this and he said he seen A toyota camry and a stock Accent to this. Basically the cold air in the winter time is so dense that the throttle body freezes and stays full throttle especially when driving on the highway for lenghty period of time. Happened when it was especially cold outside... That is -15 degrees celcius.

Apparantly the RESONATOR that takes forever to remove has a function, which is to gather warm air and cold air, by doing this throttle won't get stuck and possibly freeze in the winter and, gets colder air in the summer.

Does this make sense??? I'm still putting the intake in but man will it be worth that much aggravation and headache during the winter?

Well lets see. I've had mine on for the last 2 winters. Last winter it was below zero for a few days in a row and I can't remember a single incident. I've put close to 30k miles on my CAI and have never had it cause the throttle to freeze open. As a matter of fact we drove it to florida last winter at christmas through about 6 hours of below zero temps (in the middle of the night) with the cruise set at 70 and never had an issue.

I think your buddy is pulling your leg a little.

Well good thing I live in Miami, I don't have to worry about anything freezing over lol.. But as for the hydrolocking, I know that problem personally, but hey, the dealer got me a new engine for FREE!! lol

B :D ut good lookin out though..

THROTTLE BODY FREEZING OPEN.......

well...... if you're worried about this, then I'd NOT do the TB coolant by-pass mod.... or un-do it in the winter.... preventing this is EXACTLY what this was designed for....

and a bypass valve will prevent you from hydrolocking the engine....

Maybe, maybe not, I think the situations he's experienced was when it was really really cold... by the way what kind of CAI do you have? I have the Evo Fusion one... :)

I was considering it but apparently with the Evo Fusion CAI the bypass valve is too big, the battery and the fuse box gets in the way... ANY suggestions?

[BobMs_wht2k2]

Well, if it was THAT cold, you're probably going to experience all kinds of wierd things. I remember an AIR pump on a Tempo freezing up one winter. It was around 25-35 below 0 and we were starting the cars every 3-4 hours just to keep them from freezing up when it decided to freeze up. Extreme temperatures will always causing strange incidents.

As far as slush causing a hydrolocking situation, I gotta call bs. Last winter alone I drove through 2-3 foot drifts and the ONLY thing I had an issue with was the alt belt squealing for a few seconds. If you are driving through that much liquid slush, you need to have your butt kicked anyway.

[WytchDctr]

If you have the coolant line attached to the TB it SHOULD NOT FREEZE. That thing is what keeps it from doing that, not the resonator. The resonator keeps it from rumbling. Ive never heard of a throttle body freezing from a CAI.....

[dragonfighter60]

I agree, if you havent done the tb bypass it wont freeze... if you have and undo it in the winter, it wont freeze.... Have you ever put your hand on the tb after a long drive? even in the winter? its warm enough sometimes to burn your hand.... <-- although it never had done that to me since i did the tb bypass :)

[4mynikka]

what does the tb bypass do anyways? ANd yes I tried doing a search

[hyunelan2]

I thought most people pulled their CAIs for the winter anyway? I guess more of you leave them in than I thought. That would be the single, most clear-cut solution to those semi-unlikely problems.

Don't worry about the TB freezing unless you do the bypass. TB bypass is simply putting a fitting in between the two little hoses plugged on your tb. Those hoses run coolant into your TB, that means it keeps your TB hotter because of the coolant's temperature. I know a guy who had this TB freezing problem with a 2000 stock accent, the reason he had this problem is because 2000 accents didn't have coolant passing trough it. The dealer had to put some coolant hoses on the TB to solve the problem.(remember it was fully stock, so no cai).
Personally, i drive an 2002 elantra and i do have a cai. Since i live in Quebec, winters can be pretty cold around here, the only thing about cais and winters is to simply remove it for the winter season or at least keep your air filter under the hood. This way it becomes a short ram intake, it sucks hotter air and you don't have all these problems. But the main issue with winter is slush, it gets onto your filter and freezes there, so youre filter becomes clogged. Slush and water are way more dangerous than cold air, if you're too lazy to remove it for the winter season and you're afraid of water, you can use a bypass valve, but your cai will be a little less efficient.

[4mynikka]

Thanks Mil, I'll work something out..... and your right quebec has much crazier winters than we do here in toronto. I'll probably try getting a bypass valve if I can get one cheap....But i want to keep it on all year. :) Salut.

[dragonfighter60]

just to answer you question from earlier. the tb bypass is rerouting your coolant back into itself instead of going through the tb. it cools down the intake air and im sure you know the drill with that. it does its job giving a slight amount of power. <-- i emphasize slight

If your CAI has 3"diameter, let me know, i have a brand new AEM bypass valve to sell.... ;) Mine is 2 3/4" so it's useless for me. If you want a safe intake design, you can do as i did(because i was tired of removing if during winter), i moved my battery a little and put the air filter where the opening to the fender is. And i simply use a heat shield for the air filter, i didn't dynoed the before and after, but my butt dyno tells me that i don't see any difference, it may be a little less efficient but i think that using a bypass valve would give me almost the same result. I can send you pics by e-mail if you want to.

[4mynikka]

cool thanks... But I have the Evo Fusion one and it too is 2.75 in diameter. please e-mail me the pic. rtacorda@ryerson.ca Btw WHERE did you get the heat shield?

thanks. :)

[KeWLKaT]

heatshiled i see on ebay.

personnally i have the injen one, but i MIGHT be selling it soon, so keep tuned....

the thing is i feel like the 2.5'' intake diameter creates SOME restriction still, I will steal the 3'' civic one off of my friend who is upgrading to an AEM v2 :drool: so yea basically the filter won`t fit in, i am GUESSING it will fit 2.75'' filters, depending on how big the ``outlet`` is...

EDIT: i measured it now, you can fit a bit more than 6`` of diameter in there, so it all depends on your cone filter size!

Do you have a pic of your heatshied and I got dibs if your selling it.

this is pretty much it, i will put it in marketplace when i know it wont fit for sure though... and you got dibs dont worry :)

It is not too big, I have the evo fusion cai and an aem 2.75" bypass valve, the battery won't sit in the tray strait but it's there and the hold down clamp on the battery is tight enough that it doesent budge and the fuse box is not really in the way. It won't fit if you don't cut the pipe, which you are supposed to do as the template for the pipe cut comes with the instructions with the valve.

Alright i have a aem cold air intake with no bypass for 2 winters and no problems with anything at all just have to take some caution when you drive.

[Vampyrate]

i had mine in my sedan and drove it long before i got a bypass for it. if you feel worried about hydrolocking, get an AEM bypass. there is proof that they work, when the designer of it tested it on his NSX and fully submerged the air filter.

[Jonny666]

I have driven my Tib 2.0 (same motor as your elantra's) through 2 canadian winters with a cold air intake. at aprox -40 deg C i had an issue with the thermostat freezing shut. the trottle body didnt even think about freezing open. I havent even gotten a CEL. I however have not done the coolant bypass mod.

[only1db]

this is the dumbest thread i have seen in awhile!!

there is no way that if you have your TB connected to the coolant line that it will freeze!! air is not THAT dense that you would need worry about it...

i dont even know why i dignified this thread with a post...
