AEM Bypass Valve

Finally i installed the Intake, i was wondering if my Intake is the first generation or the second? Where i live rains often so i need to install the bypass, but i dont know what kind of bypass i need.

Once i install the bypass valve, can i remove it at anytime?? and use the Intake without it? ,here is a picture of my Intake , please guys tell me what to do and what generation is my Intake?

Bypass valve's aren't worth it. Our 4 cylinders don't have the force to suck water through all those bends our Intakes has. Honda's have problems w/ hydrolocking due to how straight their pipes are, but not us. AEM bypass valves suck the most, a buddy of mine went through 2 just because its a plastic piece of shit. He now has an ebay one which is much better and cheaper. Just remember if you run over water, just let off the throttle and you'll be just fine

hydrolock is very uncommon...you pretty much have to submerge the entire filter underwater...which is obviously pretty hard to do unless your stuck in a flood or hit a really deep puddle.

if it doesn't flood much where you are, i wouldn't bother with it.

First of if the engine is on even if your not pressing on the gas the Intake is sucking air in so letting off on the throttle will not do anything.

Second is possible to hydrlock the car I did it on the turn pike on the way home just from constant water being splashed up. Now granted I did not have any body plastics but I just got my car back yesterday from this it's definitly possible to do.

My GOD you two are friggin IDIOTS. How many posts have you seen on this very site describing hydrolock? Small, 100 hp 4 banger engines can suck water through a 3 inch pipe 30 feet straight up.

A bypass valve is a good safety measure, but most of the time.. it won't do much.


As for other safety precautions; shift early and keep the RPMs VERY low. The less RPMs, the less chance of hydrolock. A bypass valve will help if your Intake gets submerged- and only then at low RPMs.

Get one (better than AEM) when you have the chance.

Don't follow close behind other cars, avoid pooled water where you can. Be especially careful first rain after a dry spell

Ok, where i live it really rains a lot during the year, so i think i will install the bypass valve just to avoid unnecesary risks.

Lets say that i know that is not going to rain for a month, once i have install the bypass, can i take out the bypass and use the Intake again without the bypass?? and whenever i know its going to rain again install it with no problems???

let me know pple

Thanks to everybody

I Have an AEM CAI But no Bypass valve it rain semi often im from va. I ran water through the filter straight under a nosel in my sink and the water did not got through hardly. only when I turn it up full blast and put the filter up to the nosel did the water go through and mostly on the sides. but yes you do have to drive cautiously and keep rpm's low if your really worried get a slash guard thumbsup

you can always take the bypass valve off and put a silicone sleeve
