Hood Vent/Louvers question

Hey guys... just wanted some feed back... i want to do hood vent/Louvers... but everything i see allows water or snow to enter the engine bay. So i did some research and found these. They are from eTrailer and they are use for trailers for venting. I liked they way they would work on the Jeep. Cause i can manually close them when the weather does not cooperate. What do you all think?

water in the engine bay is a non issue. anytime you drive through a puddle the engine bay gets soaked. i've had genrights 3 vent kit on mine for 4+ years

I like them, but couldn't you (shouldn't you) rig up an a-frame on the hood with a series of pulleys and a nylon rope back into the cab so you can open them manually without getting out of the jeep? Say you are wheeling extra hard that day and you are on a super tough rock, you could pull the nylon rope, and actuate the pulley system, and then they would be opened and save your engine from all that heat without having to leave your drivers seat. Or better yet, an electrical solution of relays and electric motors for both up and down (open/close) of the covers. I bet you could wire that in about an hour.

I don't like them at all. They look like dryer vents. Never mind that you are solving a problem that doesn't exist. Your engine gets wet from below every time you drive in the rain.

Looks like ghetto Fab. I have louvers on my hood and yes the engine does get wet but guess what , It got wet before I added the louvers also. Every puddle you drive through enters via the wheel wells .

I considered hood vents. But there is several square feet of open, unobstructed space under our Jeeps where the 4000+ cfpm fan quickly blows radiator wash and excess engine heat.

When the engine is off, I suppose it allows some heat to escape.

Are the vents to make the owner feel better?
Is the engine negatively affected by heat when we park?

Living about an hour from the hottest place in the hemisphere and never experiencing heat related issues, I question the need to cut holes in the hood to "let the heat out"

In fact, maybe the factory engineers who are here where I live right now testing and experimenting with new vehicles intended to direct the heat down and out vs. up.

Maybe they want that rush of belt driven air to wash over the exhaust manifold and exit away from the intake or fuel rail.

I don't know.

I do know if rain or snow creates issues, there's a problem.

There are things other than the engine under the hood that benefit from staying cooler. Heat rises so addition of vents in the hood let's quite a bit out. Personally I see it as akin to preventative maintenance. And I don't see a downside even if we're wrong and there is no upside.

Heat makes plastic brittle and our TJs are getting old. I do feel better believing that my plastic connectors in the engine bay will survive that much longer.
