I am looking at buying an AEM cold air intake kit, but really worried about hydrolocking. They sell an accessory: Air Bypass Vavle. http://www.tirerack.com/intake/detail.jsp?...02&autoModClar=

Do these do a good job of keeping out the water, or should I just stray away from cold air intake?

 

the air bypass valve defeats the purpose of having a CAI

 

I thinks there is a diy for making an umbrella shield for this intake plus you could always get a injen hydroshield too.

 

Is there power loss?

 

ive never had a problem with my aem v2... but then again i dont really drive when its wet out... unless i get caught in the rain

 

personally i don't think you need to invest in this, many people find that teh umbrella is enough,

Some guys here claim that it needs to be submerged under water to make a hydrolock...

According to my experience.. if I just wash the car and the guy sprays water on it... barely.. which makes it wet only.. the car response becomes bad..if you do WOT.. I guess sucking air with high pressure allows few water drops to come in.. and you feel like the car is hesitating .... when it happened I stopped ... dried the intake filter.. than drove again.. everything was back to normal...

So.. yes you have to worry about that .. I make sure that when I want to wash the car.. to cover it.. from outside.. because I have my bumper open for it to have air coming straight in.. so I cover it with a sponge.. when it rains I keep the sponge on it also, and make sure I don't do WOT...

And yes the bypass filter defeats the point of having cold air intake..because it sucks hot air that is coming from the engine too..

It is a lot better than other intakes when it comes to gains...specially if you have a configurable EMS.

 

I have run my aem intake for about 25000 miles now every day, rain or shine. I even have the false vents in the bumper cut out so the filter gets cold air blown over it. I have never had any problems with water, rain, etc. I'm sure the filter gets wet when i'm doing 80 on the freeway in the rain, but so far no problems. The inlet pipe on the filter has a duckbill(one way) drain in the pipe at its lowest point to let any moisture out. I think unless you completely submerge the filter you will have not problems whatsoever.

 

Don't bother with the bypass valve, just avoid driving through foot deep puddles and you'll be fine.

I've had mine on for years I drive it rain or shine and never had any problems.

 

Never had problems with my Fujita and it definitely rains in Houston but I do avoid standing water/puddles/etc and my liners and fake air vents are in place and intact.

If you're really worried about hydrolocking then look into the K&N FIPK.
