Yes there is a big lack of info on these. There is a hole under the hood that should be plugged to avoid hydrolock.

wow, thats very alarming.

^ Agreed!! Especially since I can't park in the garage right now. Anyone have a pic of where the water is getting in? Or what needs to be plugged? Disturbing...

If you have a CAI and are parking in the rain (or washing the car] - try and park so that the car is facing downhill (front should be lower than the rear). This will lessen the water that can collect in the cai pipe. I think the v2 comes with a one way check valve in the elbow that's supposed to let water drip out but a lot of owners seem to plug/block it!

If you're ever parked in the rain and your car doesn't start on the first try THEN STOP TRYING IMMEDIATELY. I believe you can pull your plugs and then crank the motor to expel any water that's in the cylinders to save the motor at that point, but if you keep trying you will end up with a hole in your block

Also as was already mentioned, plug the drain hole between the fender and hood that's above the filter.

I've had an aem v1 cai on my car for the last 4 years without issues but you need to keep the above points in mind

Obviously, you have much more experience than I do, but I'd disagree and say you won't know the cause until you get the motor out and pulled apart.

False, if the design of the intake contributes to engine failures (like many people here suspect), it's a bad design (bad part). Part of the intake track's job is to prevent unintended debris from entering the motor. Usually this is handled by the filter, but in this case it looks like the routing of the intake should have been considered.

If it is a necessary compromise recognized by the designer, and they fail to make note of it, it's also bad documentation (bad part AND lack of knowledge).

I had one of these intakes installed on my AP1 when I bought it. That part was ripped out the same night.

I don't understand whats meant by HYDRO LOCK, how the hell can water get in the engine if its not flooded

U mean to tell me I cant drive my 2007 in the rain or wash my car every week WTF!!!

I chuckled. Those intakes are dangerous

You can do all of that unless you have an intake (specifically the aem v2 intake) that site low down or even under a drainage area for the car's hood. If you have the stock intake you will never have a problem with hydrolock.

Its very simple. The intake force of the engine will suck water just like air.

And if there is a large enough amount of it (as in what accumulates in the lower elbow of the AEM v2) it will lock the engine due to hydraulic force.

At 2000 rpm start up speed, rest assured something will destruct.

Only takes a few tablespoons.
