Engine AEM BYPASS VALUE

AEM BYPASS VALUE

Does any one know how to hook up a bypass value for a aem cold air intake?

you have to cut your intake at a point before it dips down into the fender. you want that as high as you can get it. The instructions should tell you where to install it, no?

cut intake

you have to cut the intake are you for REAL????????????/

yes u have to cut it

yes you have to cut the pipe. if you call AEM or INJEN they will tell u the same thing. you need a pipe cutter which you can buy at home deport and etc. then all you have to do or have someone else to do it for you. just cut the pipe. and install the bypass value.

hope this help

Good topic guys I was wondering this myself earlier. ok ty guys for the info.

Where do you cut it

Where do you cut the intake because AEM does not tell us where only that It must to at least 2 feet from the filter where do you think guys I should cut this,??????

Make sure you place the BPV before the MAF sensor. This way, in the very unlikely event you submerged your filter, the MAF will be reading the incoming air correctly. Somewhere behind the battery is ideal...if you can make it fit. I know on the TRD CAI, it's very tight in that area.

For the record, hydro-lock is quite rare. It seems likes somebody always knows someone who supposedly h-locked an engine, but it's very difficult to do. The intake filter must be COMPLETLY submerged with the engine running for 3-4 seconds. Even if the filter is half submerged, there isn't enough lift to pull up a column of water that large, as long as there is at least some air entering the filter. Rain, snow, carwashes, ect. are not issues....wet filters do not cause h-lock.

Yeah.. I use to have a CAI on my previous car. We had a big El Nino weather down here where it rained all week. My filter got so wet from driving the city streets, but I was lucky to avoid the floods.

I would check on my filter every day to see how it held up to the water I picked up and sure enough it was soaking wet as I see the filter dripping water. But the car ran just fine. No problems. Actually, it is good when the filter is wet because you cool down the air that goes into your engine. I heard some racers use to spray some water through a spray bottle on their filter before the race to help cool the air a bit.

As long as your entire car is not halfway sumberged in water, I don't think you have anything to worry about.

If the filter gets halfway submerged into water does it damage your intake or engine at all?? I'm thinking that if the filter gets halfway submerged, the water might wash out some of the filter oil, would this happen? What would exactly happen in the event that the filter gets halfway submerged? Does the water actually travel up the pipe or does the air only get sucked up in the section of the filter that is not covered by water?
I was seriously thinking about buy the aem bpv too, just want to know more info on it.
Thanks.

oil and water dont mix... so water isnt going to wash off the oil. The water would have a tough time traveling up the intake with all its curves... also it will take alot of water to "clog" the filter. and yes... the air will just go through the filter where there isnt alot of water. Unless you live somewhere where it rains ALOT or your just one of those people who constantly worry about things... you dont really need it, but it never hurts. Its a good investment, but the downside of it is you have to cut something you love.

I had a bypass valve in my last car, and to be honest never needed it now that I look back.

Well I live up in Vancouver Canada, and it rains alot here, a little reassurance would be nice too. I also heard that the bypass valve slightly decreases the performance of the intake. Ahh...still deciding....Does TRD cai warranty cover hydrolocking??

Like everyone else says, the CAI would have to be COMPLETELY submerged for a hydrolock situation to occue. And yes, the Bypass Valve does decrease the performance, but the difference is so minimal that you can't even tell.

If you want pics to see the bypass valve, hit my cardomain page at the bottom of my sig.

what he said is absolutely true i've had my AEM CAI filte 1/2 submerged cuz my sub floods since its still under construction. i never could figure out what size BPV i needed so i sold it. if you know what size it is please do inform us. that's helpful info that can go into the FAQ's

No the TRD CAI is not waranteed for hydrolocking, infact the car in its stock form is not waranteed for hydrolocking, so either way, weather you had stock or aftermarket intake and the engine got hydrolocked, you would be out the money to repair it....

2 3/4 is the size to get

sounds good, i may be getting one soon. If i didnt live in ohio i wouldnt worry about it so much, but it literally went from 60 sunny, to 30 and a fricking snow day in the middlle of march.

really? i thought toyota's trd warranty covers any damage due to the intake ... so if you suck up water due to the intake ... shouldn't it be covered?

For peace of mind ... $50 is nothing !

I asked my dealer about it, they said that the warranty "MIGHT" not cover hydrolock. But from what I read hydrolocking would be really rare, even though I have a friend that did. But on our cars, the water has to reach almost up to our headlights in order for it to hydrolock. I think i'll just take off my CAI during rainy season and put in my TRD filter.

In case u guys didnt see this, its a good story about testing the BPV. If the NSX didnt die, we should be fine.

Just get a short ram intake if you are so worried about hydrolocking. Most of the major manufacturers of CAI say that the 03-04 Corolla does not get any noticeable gains anyway when you have CAI. That is why they only make or offer an optional short ram intake for the Corollas. Sure, the CAI may offer a bit cooler air during the winter season but when it gets hot during the summer time, think of all the hot air from the pavement being sucked into your engine. That defeats the purpose of the CAI.

I would just get a short ram because it easy to install, hassle-free during the rainy season, sounds louder, and performance gain at lower RPM due to the shorter distance for air to travel.

so ur saying that if i wanted some hp increase i should just get an SRI instead of a CAI?

Well...the heat coming from the engine is not all that much cooler either.

It's up to you what intake you like to have installed. I personally like the short ram. I notice in magazines and some of the auto shows I notice that most cars have short ram intake instead of CAI. Especially on the Civics and Integras. I guess it depends on the car you have. I believe that the short ram is better for the Corolla than the CAI, but that is just my opnion. If I had my short ram K&N Typhoon intake installed back on, I like to cool down the intake pipe by adding some insulating material to help keep the enigne heat from heating up the pipe, to prevent the air from getting warmer. PLus, my filter is much cleaner, and I don't worry about getting my filter drenching wet on rainy days.

So what would you say to getting this short ram intake? http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2470752502&category=38634

For that price, I would definitely get it. If I didn't already have one, I would bid on it right now. I love the loud sound from the short ram.

Really... so how come TRD made a cai instead of a sri?

if you have 7inches of water going to your car ... i think there will be other things to worry about other than water going up your intake, no?

but anyhow i live in socal and it isn't mcuh to worry about

I guess TRD thought the CAI was more popular because Cold Air Intake sounds cool and people think of getting colder air into their engines by getting a CAI. But seriously though, are there really a siginificant difference in performance regardless of CAI and short ram? I know they both have its advantages and disadvantages and weigh each other out, whether you want more power at the top speed or at the lower end. I'm sure it runs more efficient than the stock setup and I think that's the bottom line.

Ya id have to agree to that. IM probably going to get that ebay one sometime soon. Ill let u know when/if i do.

ok first of all even if you CAI were completely submerges it shouldnt have enough vacuum to suck the water all the way to the engine unless you have the supercharger or unless you have the engine pegged when it submerges. and as to were to cut to install the AEM bypass valve... i cut my ingen cai right after the MAF sensor and before the bend that takes it aong the fender. also works good for using it as a short ram. hardest part about cutting the intake.... if you want to take the bypass valve out and run the straight cold air intake again it is extremely hard to find a 2 and 3/4 coupler for the intake. i had to order it from ingen.
