After having a cold air intake on my car for two years, I have had enough problems related to it that I can honestly never recommend one to anybody unless it is a weekend prowler or track car. Problems for me started the first winter after installing it, car would shut off while I was at speed. Had to do a rolling restart about three times a week. Fired a bit of non cl. Brakleen on the MAF and everything was fine. About a month ago the car wouldn't rev past 4k after a heavy rain. Lasted about four days then was fine.
What I'm getting at is I don't believe any of the gains to be seen are worthwhile on a car that is depended on. If I had another car to tool around with in dry weather, I wouldn't have a problem with it. Also, any crap that the CAI sucks up does end up in the engine. Synthetic oil essentially never goes bad, it just get diluted. Contamination from the intake plays a big part. I would rather have a hotter intake temp. and cleaner oil. Also things such as manifold wrap, heat shields, and widening the stock duct help negate any lost power. Throttle response is another benefit.
So any of you that live in a dusty/wet/snowy area, I recommend putting the filter under the hood. On the AEM CAI system, you need to "modify" the battery tray slighly to prevent the filter from being crushed. Also, when I removed the filter from the fender, the whole fender lining was soaked (it rained here). Water was also pooled on the plastic top of the filter.

Hmmm.... 20,000 miles on a Nismo CAI in an extremely snowy and dusty environment has done nothing to my car, and I have yet to ever clean the filter or even check on it. I drove through a foot of slush with with brown road grime for hundreds of miles and nothing ill happened. On my B13 Sentra I had one on there for who knows how long, and that was my daily driver so it saw everything from rain to snow to mud to dirt to whatever your heart desires. No problems.
I dunno... I can just think of tons of people that have had one with no problems. Hell, my ex's mom has one on her V6 Mustang, and that's a daily driver and as far as my knowledge it hasn't caused any problems.
Not to say that you are wrong, but I think you might be an extreme example of what can happen, and it most likely won't happen to most. Thousands upon thousands of people probably run a CAI with no problems, since it's one of the most popular mods to do, especially to an import.
On that note, moving to the NA performance section.

Yeah, I'll agree that I'm probably an exception. I'd still rather have the peace of mind and lose the few ponies.
Edit: The other side benefit, somehow by switching the tubing, it got rid of a severely annoying exhaust rasp that I've had since I put the mid-pipe on. Don't ask me how.

Yeah, unless you are running through standing water at full throttle, mostpeople are not going to see these effects.
Note I said most. I'm not calling you a liar, just isn't something you hear a lot about.

I never ran through standing water, I had it on for less than two months before road salt got to it. And yes, hydrolocking is probably the most severe, but I've only heard of it happening once.

Just go to SRI. It will solve some of the problems. Some advice though, I wouldn't spray anything on the maf! You are just asking for something to have a fit.

I did go to SRI. I sprayed the MAF almost two years ago, no problem. There are milder MAF specific solvents out there.

On the subject of AEM CAI, is it true that the bypass valve doesn't fit on the Spec V application? And is the Nismo CAI better than the AEM?

go turbo...nomore worries!

Im not trying to call bullshit. but Ive had a CAI on my civic for 7 years, through Cleveland winters and I have had 0 problems. My spev had it through a winter and summer, No problems... You may just be one of the rare cases..
Glad to see it all worked out with the SRI.

My Nismo CAI has a bypass valve on it and has been driven in northwest washington, like the rainiest area in the country, and Ive never had problems. you just need to make sure the area in the fender is sealed off correctly and dont drive into puddles. Though I can see how your experiences have set your view on the matter since youve had bad luck with yours.

OK, Some of you are mentioning having it on other cars. Did those cars have mass air systems? Thats where all my problems were at. Not hydrolocking or anything directly engine related, just the sensor. And the bypass I don't think would have done anything for me, especially the salt incident. I'm not even sure how those things work.

I hated the bypass on my Nismo intake... it looked stupid and after about a year the foam started to fall apart, so I just removed that section and put a coupler there. I don't really have a need for it, as I avoid puddles.

It's damn near impossible. Where your CAI is now is where the Cool side IC piping runs on a turbo setup

I see. Hmmmm, I wonder if you could widen out the hole in the fender and extend the intake tubing, would be a pretty tight fit though...I remember reading a tech article years back studying cold air intakes on turbos. The arguement was that the air would be heated anyway, but if it were to go in colder initially the actual temp when it reached the engine would be much cooler. IIRC it was like ten degrees less at the turbo would be 40 at the engine or something extrememe like that. Anyone have any links?

I don't think it would really matter, as long as you run a intercooler.

The bypass on my Nismo intake dried up and started falling apart after less than a year, so I took it off and just put on another coupler in its place like cute02spec did.

Well think about it. Air should only increasae a set amount when it passes through the turbo. I don't see why 20 degree cooler air at the filter shouldn't equal 20 degree or more cooler air at the engine. Why whould cooler air be heated more (20 degrees in this example) ?

My friends' spec got hydroblocked yesterday and as soon as he told me I KNEW it would be better to convert my cai into a sri for the winter so that's what I'ma do just to be safe.

Seriously, WTF? Do people just see a big puddle like two feet deep, decide to risk it and drive through it, and then start revving, going "I'ma gonna get a hydrolocked engine today I tell you what!"? It's not that hard to avoid big puddles, which is what every driver should be doing for safety.
I've driven in plenty of rain in my Spec, and never once did the thought cross my mind of "Geez, that big puddle looks fun because the water is like a couple feet deep, let's go see if I can make it through with my CAI, and once I get stuck I'll just like rev it redline so I suck up water, word! It wouldn't be fun to have to drive one block farther to go around the puddle, I'd just rather drive through it!"

Lol Heidi you ever driving in cedar through the winter (the time you came to denny's doesn't count" there are very low gutters and like I said...just to be safe!

Also, around Baltimore you can get standing water that is quite deep. I myself never worried about hydrolocking it...a little water cleans the carbon out!

I have the bypass on my AEM, I had to cut down the MAF adapter to make it fit but it works. As for which is better, they're pretty much all the same. As long as the filter is decent I don't think the name matters much.

Thanks a lot. I think I'm going to get the AEM and not worry about the bypass valve.

It's totally custom made with less that $20 in parts, Plus the filter which is the autozone brand. Beats the huge amount that you would pay for AEM SRI.
I can make a heat sheild for any car, or lets put it this way, there hasn't been a car that I couldn't do one when asked.

my spec was having the same probs and i dont have a cai on it yet. It would shut off in mid drive only if i was in nuetral or at a light stopped. if i didnt keep my foot on the gas to keep the rpms up it would die. sometimes it would have absolutley no power and it was really sluggy and wouldnt go past 4k rpms with your foot to the floor in first gear. i had it checked out and it was the idle control valve and sensor in the throttle body. You can buy the parts to fix it for about 50 dollars but the stock throttle body isnt servicable cause it is all pop riveted together. i ended up having to buy a new throttle body and have the idle control sensor relearned cause it was idling and like 1500rpms. it cost me about 225 dollars to have it fixed.

I live in MD as well and like most poster I haven't had CAI problems after 32k miles on my '06 Spec. I did, however, get around to cleaning it the other day; I found some serious debris all over it (a pebble, two flies, one small puppy, and a walker. No sign of the geriatric it belonged to.) Sorry to hear about your troubles though.
I'll need to remember Heidi's coupler install tip. My bypass section hasn't begun to deteriorate yet but when it does I guess I'll know what do do! Like most of you, though, I avoid puddles like the plague.
Cheers!
