I have an unknown brand of a cold air intake, and I recently learned about needing a bypass valve to prevent water from entering my engine. I was wondering if anyone knew where it needs to be placed, or if there is a specific place at all. My dad asked a couple guys that said that we could put it right after the filter, but then why would AEM (the manufacturer of my bypass valve) include a template for cutting the tubing of a 3" intake?

 

You can put it anywhere on the pipe as you please. Just cut the pipe somewhere, and place the bypass valve there

 

i have heard bad stories about that bypass valve.
i think it would be better to just have a two piece cai
that you could easily change to a short ram in crappy weather
or just make sure that your splash shield is intact so
no water can get in there

 

i have an aem bypass vavle for sale if u want it, its 3in. e mail me if your interested in buying it r3dh22@hotmail.com

 

I wouldn't run a bypass valve. It only helps when you completely submerge your intake in water. Now why would you do that? Unless you have a habit of driivng in lakes you are usually okay. But it's all about your comfort level. I would be worried about the valve leaking dirt and air etc..when not in use

 

You're fine without one as long as you have you don't leave your splash guard off.

 

another post tellin you NOT to get it.

i have the bypass valve on my aem cai. as stated above, it only works when the entire filter is completely submerged in water; it does NOT protect against splashes or partial submerge of the filter.

it's a waste of money. i wish i hadnt gotten it.

aem recommends putting the bypass valve right near the distributor cap. but then again, that is like the only spot it will fit anyway in the engine bay. and yes you do have to cut your intake piping..... ghey.

dont get it. and dont drive thru a river.

 

i dont like the one on my gsr...it makes the intake really quiet though......but id say go without

 

yea the bypass blows, definite decrease in power, and I've driven through some monsoon type rain storms with no splash guard and no problems.

so bascially...almost everyone's telling me that it's not good. i've driven through puddles and rain before, but I can't remember if it's ever been really, really hard rain. i still have my fender wall, so what if i just got a splash guard?

 

You already have a splash guard it's not an upgrade or anything.

 

i wouldn't rock one but if it helps you sleep at night then do it... it is after all your car

 

the chances are you wouldn't be getting hydrolock
but you could, that's why i invested in a bypass valve.
maybeone horse power lost but it's better than buying a new engine.

some of you guys makes it sounds so unreal, it doesnt take a large body of water to get water up the pipe. the theory is that you need to stick the whole pipe in the water and rev' it up, i was a believer until i know someone that got their engine hydrolocked, no it wasnt not a heavy rain, no his filter is not submerge in water, no he's not rev'ing the motor high, and no, he got his oem bumper and splash guard there too.
it's better to be safe then sorry, that's the way i see it.

search around, there's a bunch of ppl with hydrolock engine.

the placement of the bypass valve is suppose to be the same height as the throttle body assembly, about where the AEM stickers at, but again, depends on the application.
