This is the real answer:

subarus have been in rally's for as lnog as it has been around. i really doubt that water coming in from the top of the engine will ruin it because that would just be *****. everything is sealed. wrxs and stis have holes in the hood and let air in, water gets in too when it rains. water also gets in thru the huge hole underneith your car. it is water. unless you suffer from the problem a very select few have, (instant combustion, hahaha ) you will be fine.

the only thing i would look out for is the vent over the battery and that is only an issue if you have a stock battery, if it is an issue at all. i just know that my battery is jank (stock) and already has corrotion on it.

in regards to water getting into the car all the time, even with the covers on. my engine bay gets wet with them on. i keep them on in the winter, drop them in the summer. during the winter, they leak, always have. they are cosmetic, i really doubt there would be any negative effects by taking them off, or the scoop.

it is a personal preference, and no matter what you do, in the time that YOU own the car you most likely won't see any side effects so who cars ... i know you have an air filter next to one of the vents because i have seen your car, so i would watch out for that. the scoop, will be fine. the only other way that i could see a problem occuring is that there is a short somewhere in your electrical, in which case, its a problem with or without water

edit: there are people on rs25 that have had them off since the day they got the car, and have had ZERO problems. i really dont' think that it is a big deal no matter how you look at it. they dont' do anything with them on, and with them off you get minimal temp drops if at all. if you do this in the summer like most people, you don't get much rain anyway so it's def. not a big deal.

I would have to think it's a warranty thing. So, people can't say "It rained on my engine and it blew up, give me a new one. With the rain cover on, when people say, "It rained on my engine and blew up.", the manufacture will say, "Did you take the rain cover off? You did? Well, you're beat. A new engine will cost X amount of dollars." I would have to think it's just to cover their rears.
If you want to talk about why manufacturers put things on without having a purpose, lets talk about the scoop on a NA engine. Why did Subaru put that on? It serves no real purpose but to look "cool". What would your engines without a weather cover look like? That's right, "uncool". So, it could just be a cosmetic thing, also.
As far as water getting on the engine, I think you'd be fine as long as it's not dumping bucket fulls of water all over the place. I wouldn't want my intake filter, alternator, or plugs getting anywhere near large amounts of water.

and it would take a long time correct me if i am wrong but my 98 OBS has a hood scoop and so they have had scoops for over 6 years and i am sure taht there were a few that took off the weather covor and there has not been anybody complaining about it... i would say that is a long time (6 years)
How would they know that the hole in the hood was causing their problems?

I put more trust in the people who have been designing cars and equipment over the last century or so than I would in your random sample of Subaru owners.

Let me try again, are the manufacturers of vehicles and outdoor equipment wasting their customers' money by putting weather shields on their engines?

That all sounds reasonable, except for the comparison to hood scoops. Subaru puts those on because they figure that people like how they look. I don't think that cement mixer manufacturers are interested in the cosmetics of their weather shields. Those silly devils seem to think that a motor does better when shielded from the rain.

Agreed. The thing I don't understand is why someone would go out of their way to put a hole in their hood. The downside of doing it is probably minimal, but the upside is zero, IMHO.

its is pretty lame having a completely nonfucntional hood scoop, so taking it off so that you can at least see in is nice, lol.

oh and if you blow up your engine because water got on it, do not say that you had your covers off, put them back on before going to the stealership, duh . then be like, *** you asses, you gave me faulty rain covers

You're right about the downside being minimal. The upside, has been stated before by the gentleman who took it off. More air flows into the engine and it would allow a spot in the hood where hot air could rise out of it, essentially keeping the engine cooler. Whether or not this actually works is another thing. Theoretically, I could see how it would work.

If you have a cold air intake which like has so many bends and goes all the way down from your manifold to your fender, there is no possible way that rain water will be able to go through the filter and travel all the way up to the manifold, is there?

I can see the hole in the hood being of benefit if you are idling or stuck in traffic on a hot day. You ever notice how cops will slightly open the hoods on their cruisers if they are going to be idling for an extended period? Your hole in the hood would have the same benefit. Otherwise, I'm going with the factory-designed cooling system. If there was a benefit from having more air go through the engine compartment, it would have been easy for them to put in a functional scoop with baffles to keep rain out.

What long-term effect does the freezing/thawing cycle have on cars with holes in their hoods?

If that is an issue, I think it is going to be just as bad on cars without holes in their hoods and those with holes. IMHO. My guess is that you wouldn't have a problem either way.
