is it necessary on my 5gen or can i go w/o it

 

Unless your going thru excessively deeps puddles you don't need it. You will only suck up water if the filter is submerged in water. If you feel uncomfortable running in wet weather with a CAI, you should be able to disconnect the intake on rainy days and adapt it to Cool Air by putting the filter under the hood. Most CAI are two piece that disconnect under the hood. Hope this helps.

IMO I would never buy an intake bypass valve. I have heard too many stories of the butterfly valve being sucked into the intake.

 

save the 40 bucks use it for gas or you can eat at wendys for the whole month! I had a AEM CAI on my car before i bought the supercharger then i switched to short ram. I had no problems for a year without the bypass valve.

 

It really all depends....does it rain alot, does it snow alot, do you drive when it happens??? i'm always paraniod and i got it....its better safe than sorry than to pay for new cams etc because water is to condence..which burn up ur cams...just get it...be safer...

 

I've got the bypass valve on my fourth gen, and to be honest there wasn't a noticeable difference with it on as opposed to running without one. I live in Florida and it rains all the time, so I decided it to be a better investment rather than replacing parts. I think it really depends on the weather conditions in your area. It's a sound investment, but in some area's I'm sure it's not necessary.

 

YEP!

 

dont buy

 

There is without a doubt in my mind, a noticeable difference without it. I had it on my type-r, and recently removed it, and man is it better. Now you can really hear the growl of the 3" aem. There was numerous dyno tests done that show a few hp loss with it, but if it's going to save your engine from disaster, it's surely worth it. You'd really have to go in deep, at full throttle, to suck up water to cause a hydrolock. I hydrolocked my thunderbird 10 years ago, and it was not pretty.

Another downside, is the amount of fine dust and dirt it allows in. My intake pipe was noticeably dirtier when I removed to uninstall the bypass. I took pictures and all, but only because I saw someone else on the itr board with the same dirt; only after the bypass.

I guess if you think you may drive into a 2-foot lake sometime, then get it. If not, don't waste your dinero.

 

Is referring to the bypass valve on an aftermarket intake, or the secondary Intake Air Bypass Valve on the Intake Manifold? Two different things entirely.

 

A little confusing. The IAB on a stock intake down in the bumper ? the butterflies in the IM ? or AEMs valve ? Everyone went the AEM route.

 

I think we are all discussing the aem bypass valve. I don't know how the butterfly valve can get sucked into the intake, as mentioned above. I think he may mean the filter gets sucked into the intake, and can lodge itself in the throttlebody butterfly, causing your accelerator to be stuck open, which=bad.

 

How did you get that from "is it necessary on my 5gen or can i go w/o it"

 

I don't think I understand you here. I was responding to the questions above. Where did the secondary runners come into play with this topic? Maybe someone can help with the translation?

 

No, you don't. By the initial post and topic title he could be talking about several things and that was my point. Everyone assumed it was an AEM Intake bypass valve, and he hasn't come back to clear it up. But that could also be IAB - Intake Air Bypass Valve.

Get it? Sheesh...

 

satan_srv i was wondering the same thing when i first saw this post but i chose not to say anything because everyone went the other route.. where is the starter of the thread?

 

It should be pretty obvious as to what he is referring to. Hence the word intake, it should point some fingers regarding the bypass valve question. There were 7 replies to his question, all answering the question whether or not to use the bypass valve on his 5th gen. Why you chose to cop an attitude to me, I don't know. Next time, check it at the door.

Why don't you goto the search button, and search for "bypass valve", under archived topics. You will see 38 posts, just about all referring to the cai bypass.

 

I think the starter of this post got the answer to his question, otherwise he would have most-likely specified which unit he was referring to.

 

i dont think anyone got an attitude with you apexii, please dont be so defensive he was just trying to be clear on what the topic was about so that we could answer the questions correctly.. and the intake manifold question has benn discussed a few times...

 

IAB = Intake Air Bypass Valve, I don't understand what's difficult about this. His wording is ambiguous. I could care less if it's a popular topic, I was merely pointing out the ambiguity of his question. I don't know what the hell your problem is.

 

Thanks for pointing out the ambiguity to the question. It must be a new word for you. Again, my comments were to a poster above regarding getting sucked into the butterflies. This is pointless now, I think we all know what the question was referring to.

ps, I don't have a problem, but I now see you do! You're the one who came at me like I didn't have a clue. I think you know we all were talking about the cai bypass, not the iab, you just felt like throwing in a comment like all 7 of us were not talking about the right valve. I clearly understand the ambiguity of the two. Whatever, again this is a pointless discussion. I can have a mature discussion about this, but not if i'm the only one doing so.

Viz, I said nothing defensive to you. I think the statements directed at me were more than in a defensive manner and I even replied in a corteous manner; saying I was merely responding to the comments in the post above mine,

I'd call that antagonistic! I never once "didn't get it". I know preludes like the back of y hand, there was never a question as to wether I understood the two valves in discussion.

 

I was never referring to you or came at you, my inital post was at the post starter. Just because it says (apexii) in the reply just means I clicked the last reply. It was never directed at you so I don't know what you're talking about.

My first post: "Is (he) referring to the bypass valve on an aftermarket intake, or the secondary Intake Air Bypass Valve on the Intake Manifold? Two different things entirely."

At what point did you glean it was directed at you? Start from the beginning and read again...and don't tell me you're trying to be the 'bigger man' here with condescending statements like this, the bold was a nice touch jackass, but intake and bypass despite being bolded could refer to the IAB...you stiiiiillll don't get it. I'm antagonistic?

I didn't say I was being the bigger man here, but I guess it's apparent to you. I've said enough, again this is a pointless argument. I'm finished discussing this with you, reply all you'd like though.

[edit- well, considering you've edited your post 3 times now, i'm responding, but i'm not going to join in with the namecalling, sorry. I really love how you are rethinking and editing your thoughts after you posted, lol!]

yeah sometimes you write and then rethink it. You're right it's pointless, you should not have responded to something that wasn't directed at you.

 

sorry for the confusion

i meant aem bypass valve

 

Air Bypass Valve
AEM’s Air Bypass valve for Cold Air Induction Systems virtually eliminates the unlikely chance of water ingestion should the filter element become wet from deep puddles, rain, hail, sleet or snow–or any other scenario in which the filter element could encounter or become submerged in water. The valve installs along the upper portion of the inlet pipe on the same axis as the throttle body centerline. Should a drop in pressure occur within the pipe due to filter submersion, the valve shuts down induction at the filter and routes incoming air through its external orifices, eliminating any chance of water ingestion.
AEM’s Air Bypass Valve is for use on AEM Cold Air Systems only.

The above paragraph is from aempower.com
The butterfly I was referring to is the valve that shuts and reroutes the air. I have read on several boards about these valves coming loose and being sucked into the intake. Thus causing stuck TB and other mishaps.

I'm sorry I said butterfly when I should have said valve. Sheesh!!!!
