Default water in intake! how to keep water out - let air in

so I have had my 2 hood vent and the scoop gaurds removed almost immeadiately after i received my RS but recently with alot of rain the intake has been getting water in it. I reattatched the gaurd over the intake today to fix the problem but i was wondering what my other options are to getting cold air into the engine bay around the cone filter.

I have a AEM short ram intake with K&N cone filter

can i get a bypass valve and then remove the vent gaurd again or will i have to cut the intake in half?

I was thinking of maybe routing some ducting from underneather the turn signal up to the cone filter....?

also do i need to replace anything for installing aftermarket cams on a 2000 rs 85k miles ? and what is the best BIG cam for lots of power

this doesnt make much sense, why did you remove the shield if there is no intake there? the aem sticks over by the fenderhole doesnt it? by removing those shields you really arent getting anymore airflow to the engine could be even making more drag i think

I do the same thing only my intake sits right under the vent. I'm sure it really doesn't do anything but I'm sure it cools the motor better and the intake is louder. When I know it's gonna rain I put only the one on that protects me from blowing a maf sensor. Next time just watch the weather and you'll be fine, make sure when it starts to rain you put it on.

a bypass valve isnt going to do anything..if the intake is getting alittle wet dont worry about it.its not going to do anything.
I havent had my vents on my car since I bought it and I drive in all sorts of weather.
with the vents off it relieves negative pressure in the engine compartment, whe you are driving the air flow comes into the engine bay and has no where to go , with the vents out, that airflow goes right out the top.

I have a K&N Airfilter on my car the day I bought it. I opened up both airvents and the hood scoop. Didn't really notice a big change, but I am now hearing a whirling sound after 3,000RPM's. As the RPM's get higher, the sound gets louder. I tell my friends that they are hearing my turbo . I put one of the airvents that covered the battery back on so it does not get wet, and cause damages. That was a smart move when living in Washington.

I got this shield that blocks water from entering from the top, but not from below the car. I can take a picture to show you what I mean.
