The guy at a local garage told me that a year or so ago, the owner of AEM brought his NSX to the shop to demonstrate how well the bypass valve works. He said the guy submerged the filter from the cai into a bucket of water, started the car and revved it for a while. Shows how much faith the guy has in the product, if it's true!

chances that you'll get hydrolock are not good. you're not going to get it by water splashing on the filter. if it were to be possible, you'd have to completely submerge the filter, and probably rev your engine tro increase the intake response. with just water splashing? it's not gonna collect into a water ball and shoot up in there. just don't drive though puddle that even just barely touch the front bumper.

the bypass valve will decrease the amount of hp and tq recorded by aem.

Personally, I don't think the 1 or 2 Hp difference is big enough to warrant going with a CAI on a daily driver. I would rather use a volant and know that there is very nearly NO chance of hydrolock, than go from 100whp to 102whp by risking my engine. That's just me, and I live in Maryland where the saying goes, "if you don't like the weather in Maryland, wait five minutes". So, with the stupid weather, high water-tables, and everpresent lakes masquerading as puddles, I'll stick with the Volant.

I am lowered 2" with a CIA If I go threw a puddle I try to coast threw it. Or just go around it if at all possible. In the Rain I Remove the Crank Case breather tube. The one that is connected to the head and that makes the connection to the intake a foot or so before the filter to make a open vent to stop hydro lock... maybe in an idiot but o well...


But hey I don’t know “This” car so well yet

OR I may get a crankcase breather and put in a valve so I hit the valve and breather opens to stop hydrolock..

SEE PIC

You will not lock an engine up due to splashing water. If any water did get thru it would be a small amount an evaporate. If anything get the shield, to make yourself feel better and go longer between cleanings. I will stick with my aem cai w/o bypass valve and feel safe. Like ppl have said unless you submerge it you will be ok. Submerge and sit, not splash or puddles. It takes more than a few drops of water to lock up an engine.

Straight from AEM's site

The AEM Bypass Valve is used to protect the engine from hydro locking. Hydro locking occurs when the end of the inlet pipe is submerged in water and the water is sucked into the engine. Driving the vehicle in rainy conditions is not enough to cause a problem unless the vehicle becomes submerged enough that the inlet end of the pipe is immersed in water. Rain impingement on the filter will not cause a hydro lock condition. The distance of the filter from the road dictates the level of water that can cause damage.
