a bypass valve is essential for any air pickup outside the engine-bay.

How do those things work?
It allows the air to be attained from the bypass because it is essentially a filter. Correct me if I'm wrong but if you have that in your engine bay, the 'cold air' will be canceled out with the hot air from the engine bay...
Also, the bypass valve is works when the air filter "becomes submerged in water" -AEM. When the hell is that ever going to happen?

did you move your pressure sensor, or are the S4's in a different place than the S5's?

a liitle bit of water is drastically different from a lot of water. an intake charge of nothing but water is bad no matter how you slice it. sucking up a puddle if far different from the water trick.

no it doesnt rain much here and i disagree with the im gonna hydrolock my engine.... k&n is first well known for not letting much of ANYTHING through its filter properties and then its still a good freakin heigth from the ground... i mean sure its gonna get misty from driving in the rain but if you have a good filter and not some 9$ ebay crap then you should be fine and also the force of the air is not powerful enough to just suck up a pond... i mean take a vaccum cleaner and hold it over a puddle of water... the vac doesnt suck it up and ive used some powerful vacs too.. it just causes the watter to ripple in but not actualy suck it up.... those guys you know must have not done something right, drove thru a puddle at least 2 feet deep, or used a crappy filter.... anyhow im not worried about it because i have done this on several other cars with nothing but POSITIVE results and i feel confident my car will be just fine especially after the rainstorm i got caught in the other night coming home.. no hesitation, no stalling, no nada just my car running like a champ the way it should.... lets not go into a big argument for it. you have voiced your opinions and severl others have theirs lets leave it at that.... have a good day and thanks for the replies guys and a writeup is coming soon.. i found a way to do it CHEAPER than the way i did it heh...

and also nobody should drive through a water puddle of any sort with a low riding sports car... thats how alot of people ruin their cars WITH THE STOCK SETUP... its about being careful and if its too flooded to drive then that sucks your stuck... if you dont like that then get a beater and drive that but i do NOT drive my car in any water thats standing cause you never know how deep it is or what could happen and always stick to the inside lane of traffic because water builds up on the far right hand side of the road.. just use common sense and youll be fine... as i said lots of people have done this and there fine even after a few accidents and hitting some water. no prob... if anybody had done this setup and had HUGE problems then BY ALL MEANS POST but unless you have first hand experience then dont hypothesize (leave that to the scientist)

water is still not combustable, in a reciprocating or a rotary engine. I'm very skeptical that it's impossible to hydrolock a rotary with enough water at WOT.

I drove threw a few puddles on purpose with my CAI. My prototype way back when sat lower than this and nothing happened to my car. Its initial test was also during rain. Unless you completely submerge the filter I doubt you are getting any trouble out of a puddle.

Looks like a great set up. I would not be worried about water with that. Where the filter is located it is probably 5-6 inches off the ground AND its behind the bumper. You are going to have to nail one hell of a puddle to get water in there.

I dont think i'd worry about water. I think i'd be more worried about debris from the road hitting and damaging the filter element allowing dirt and whatnot into the engine. Do you have anything setup down there that protects it from that?

definitly a good write up, im sick of the cone filter i have sucking in hot air, it feels terrible in the low end when ive been in traffic and it gets heatsoaked so a good cai writeup would be great.

actually the filter i have is too big so im waiting to get another one... when i have one the right size im going to put the brake ducting back on completly sealing up that fender area with the exception that the brake ducting will also be routed to the cone and have wire mesh on the end to prevent debris from damaging the filter.... a write up is in progress and will be done this weekend....

just a tidbit

here is a little tid-bit for ya...

I drove my '89 Turbo through up to the window trim in water, the front end sunk and the engine died, air box completely submerged. (It didnt look that deep...)

Once we pushed the car out of the puddle (by climbing out the windows) she fired right up again after spewing out craploads of water. That was early last year.

If it didn't hydro-lock in that situation I don't know what will.

( on the plus side the only water that leaked into my car was from a grommet hole I installed on the firewall and from the heat vents which were open for air flow, but stopped leaking water when i closed them ).

I would have made it through without the front end sinking if water hadn't have gotten in where the clutch is and started it slipping...arrrg...

Come on now, let's be realistic...
A vacuum will always release itself via the simplest path possible... so even if you submerged the bottom half of the air filter, only air would be drawn into the engine via the top half of the air filter; its significantly harder to draw up water than it is air.
In light of this, the entire air filter would have to be submerged... This means the car would have to be driving through puddles at least above the centerline of the wheels.
So... then... what other precaustions are we taking for these humongous puddles? Are we water-proof our brake calipers so that the sudden dubmersion in water will doesn't warp/crack (thermonuclear shock) the rotors and get in between the pads/rotors and keep us from stopping? Are we siliconing the car doors shut so that the water from puddles this deep does not flow into the car and casue electrical shorts?
A water bypass valve is created for a problem that never existed, and is sold completely on hype.

Let's be realistic here guys... who drives through puddles that deep, ever?
