Question about Evo hood vent
This might be a stupid question. You know those vents Evo has on top of it's hood, what's preventing the rain water or car wash water from entering the engine compartment and damaging the engine or electrical devices For Evo owners, do you have to be very careful when washing your car?

slats, they channel the water so that while driving at least it is flowing with the air up and over the hood. Also, water in the engine bay isn't bad. Water in the engine is. Your 3000Gt gets water in the bay, every car gets water in the bay. You go to the car wash and some of them even have special engine bay settings for cleaning out to show quality. It's not a bad thing.

Don't the vents have mesh on the outer most part of the hood, then mounted underneath there is a plate with slats that keep the engine cool through that whole negative pressure deal (air goes in through bumper, into the bay, then out through the top)?

What if you're on a long drive and all of a sudden it rains? I just know that when something is at extreme temperature and you introduce water to it, there's a possibility that it'll crack.
I could be 99% wrong. I doze off in some of my science classes back in high school.

also its ok to wash your motor when its slightly warm. meaning its kool to take a 5 min drive to the car wash. wait in line and then wash ur bay. driving all day and then cruising str8 thru the car wash could cause you problems...

Thermal stress results from large changes in temperature. A submersion in water could cool off engine components so quickly that they would fracture, but if your engine is submerged, I think you have other issues to address.

While you are driving, I don't think that any water can get in due to the air flow that comes out of the engine. While in the car wash, I am not sure about it. But, those openings/opening have a mash in there an that will slow down entering of the water. Also, underneath those there is a turbo charger which has a shield over it. Either way, as long as you don't damp buckets of water to it, you will be fine!
And, this is an obvious problem with the hood openings, so I do believe that spend some time and made sure that this is not going to be a problem for 12 years now!

Iron lower block...it would have to be extreme sudden temp. changes for the block crack...I don't think rain, car wash or even running through puddles can create enough of a temp change that quickly. Washing engine compartment with large amounts of water is not very smart anyways...(steam or mist is better)You'll ruin electrical systems before you ever get chance to crack your block. On side note the reverse is also true:LARGE amounts of water suddenly splashed on a cold engine during sub-zero temps can have the same drastic results.... remember the temp change has to be drastic and sudden....
