CAI + Winter

[shin0bi]

Has anyone had problems with cold air intakes on their daily drivers and Alberta's wintery climate?

I've heard from some people it's not that risky, and other people are saying its a bad idea.

What's the Beyond.ca consensus?

[JustinMCS]

I've had a CAI on my last car and on my current car 24/7/365 and no issues that I can see.

[ExtraSlow]

It's more of a problem in rainy conditions, as it's possible to suck in some water. I haven't heard an issue with snow or cold.

[88CRX]

The only issue you have with a CAI is if it gets 100% submerged in water (highly unlikely in the winter for obvious reasons) or getting too dirty from sitting in a wheel well with no fender liners.

[Disoblige]

No issues, just will get dirtier quicker when we get those very dirty slushy days.

[Hallowed_point]

I know that Injen makes a hydro shield to protect the filter from water, I'd look into that just to be on the safe side for slushy days

Not just dirtier, but outright FILTHY... really keep an eye on it and clean it often.

[manny18]

its fine unless its low to the ground and can get water/slush sucked up into the motor. but i ran my jetta like that and u just need to be more careful

[manny18]

cold air intake..... winter=colder air ---> colder air in your intake = vtec kicks in faster yo

This needs to be posted in every CAI thread on the web.

I don't think that is entirely true, people hydrolock plowing through puddles that aren't deep enough to submerge the filter, if you hit a puddle and completely soak your filter you have a decent chance of pulling in water I don't think you have to completely submerge it.

I'd just pull it for the winter if you are concerned, they don't add noticeable power, they are essentially just for show, why people risk hydrolock for appearance/sound is beyond me.

I started my rex once when it was submerged my wheels were half covered . Sucked water in and since its less dense then oil it crepped past my piston rings to my oil. I had to do 2 oil changes and break clean the inside of my valve cover .

Water is not less dense than oil...

LOL, too funny on several levels... you should just stick to your missed connections thread in the spotted section

[heavyfuel]

No problems here, then again my S&B is an enclosed style, they make pre-socks for just about every filter out there too, always good to have that extra protection. Never had an issue with mine in winter.

[FraserB]

Have a pre-sock on mine, zero issues even in deep water and mud.

your kidding me right ? you know the film when you rub oil between your fingers. and when you do the same with water you can feel your finger ? :rofl: :rofl:

I highly suggest you retake highschool chemistry. Why do you think oil floats on water????? explain that one to me.

your little "test" has nothing to do with the density of the fluid....


here, just so you don't have to lift a finger. 10w30 at 15 degrees c is 875kg/m3, fresh water at the same temp is about 1000kg/m3...

happy? or do i have to explain further...

[OriginalGoods]

oil on top of water. please explain then. i would like to have clarification instead of the rundown. :thumbsup:

[g-m]

^lol I don't think he's made it to high school quite yet. If he did, he sure wasn't bright enough to get into chemistry!

edit2: Its hard to even know where to start. You should probably just spend a few hours reading. If you had started your engine with a fully submerged intake you'd be replacing rods, not oil.

do you understand why a rock doesn't float??? and why air is on top of water??? and subsequently why oil sits on water??? the answer is density.....

as i edited in my last post:

875kg/m3 for 10w30 at 15 degrees c
1000kg/m3 for water

im sorry but do we really have to get into this?

[Disoblige]

Poor guy. Don't try to explain more to him. He knew his car was submerged half a wheel high and still attempted to start his car with a CAI.

And now people are trying to explain fluid density to him? I think it's too much for him to handle.

What's more sad: January 9, 1988 :rofl:

[lilmira]

Are you one of those jaywalking people from Leno?

[forced_eg]

lol, great thread

on a side note, do you think the oil in k and n filters gets more dense on a cold day and is more of a restriction as opposed to hot days?

[shin0bi]

In an attempt to steer this thread back on topic (though seriously?! Oil density > H20 density lol)

I think what I'll probably end up doing is just running something like this: http://www.aemintakes.com/air_filter_wraps.htm
during the winter months, and have a couple of cleaned/oiled filterheads ready for swapping in year round.

Sounds like the consensus is that smart driving and proper maintenance will prevent hydrolock from occurring.

I might even try ghetto-rigging up some kind of makeshift baffle out of polyethylene or some other plastic to redirect splashes or roadspray as well.

I may even look for an intake that can convert to SRI for winter to be on the safe side.

[sillysod]

It is clearly dependant on the type of CAI.

I have a Carbino on my A4 and had the one from Western Motorsports on my GT and both included airboxes of some sort.

If it's just running a filter on the end of an intake pipe in the engine bay isn't a CAI. more like a HAI.

[OriginalGoods]

If you have a bypass valve you will be ok . Its not hard to make one into a solid tube . Then you will be safe .

is this something you actually learnt from a teacher or is this just a joke?

[gogreen]

In extreme cold, supplying the engine with a source of warm air would actually help it reach operating temperature sooner and operate more efficiently. So drawing air from inside the engine compartment would actually be better from an engine longevity standpoint, particularly if you're making short trips in the cold.

[bignerd]

Never had a problem with winter.

Did have a problem when a summer hail storm blocked some sewer grates and also took out the power and I plowed into a foot deep puddle going 50 km/h though...

[Cos]

Never had a problem when I ran them but I probably had to clean my filter 2 or 3 times.

Are you trying to make OriginalGoods head exploded!?! LOL

I know I shouldn't continue this but, what you're describing here is viscosity.:love:

[Disoblige]

Kinda like how buttermilk can slide off a 45 degree incline at a quicker velocity than Aunt Jemima pancake syrup. So essentially, the buttermilk used to make the batter for your pancakes is less 'viscosity' than the Aunt Jemima pancake syrup you use to pour on top of your hotcakes :)

Don't mistake velocity with viscosity though. Those are two entirely different things!

[JZS_147]

You can just get an Air Filter sock if you're worried

[ZeeZee]

Agree with the sock/pre filter. Much easier to wash than a whole filter.

It may cost you a couple of HP though, easily rectified with a sticker or two...

Edit: Should have read the post before this one...
