Specificly under the hood items, i.e. bottom of Intake Manifold, C.A.I's. & etc., as to light or dark color (white/black)???

Sort of confused by what your asking but I will respond with: I think it's just personal preference. -- 94z28 D.D. slp cai, 3.42's, flowmaster exhaust, and tb bypass.

Depends on if you want to show off the engine bay. Personally I think it looks neat but I wouldn't do it. My buddy bought a pair of the vette engine cover thingies and it looked good, but for the price he payed for them he could have put that money toward go fast parts or something, I would see, useful. --

^yea, I agree. My brother in law spent $7,000 making his acura integra look cool. He thought it was sweet until he took it to the track and it ran a 17 second 1/4 mile. Me on the other hand, I didn't spend a dime on appearance other than rims and 1le fog light inserts. -- 94z28 D.D. slp cai, 3.42's, flowmaster exhaust, and tb bypass.

Thanks Guys, but what I'm looking for is, color in reference to increased performance. Does a white Cold Air Intake keep the air colder than black?
Does a painted white, bottom of an Intake Manifold, reflect heat better than a darker color?
Sorry for the confusion.

Do they make a white cold air intake(that it matters)?I've always seen chrome or black.

No, but you could easily just paint or powdercoat your own. -- 95 T/A.

painting or powdercoating pieces like your talking about will have very little to no noticeable advantages. Infact, the added material might lessen heat disepation but that would be very minor and unnoticeable. They powder coat headers and parts of that nature to keep the heat in and cool down faster, but those are high heat areas. It would be astetically pleasing, but thats about it. If anything it makes those parts harder to clean. -=] -- -xysgim

i know what he is talking about. On muscle car tv they had a special on how white paint on the bottom of your intake manifold helps keep the mani from heatsoaking, and helps keep intake temps down. But i think they were using a special kind of paint.

OK, enough of this bullshit. The original question is a valid one that few (if any) people in here are qualified to answer, much less laugh at. The best I see anyone coming up with is a simple approximation based on a general rule that heat radiated will be low compared to heat transferred through conduction/convection (which is close enough, but maybe this reply will prevent any more idiocy from digging it back up). Unless you know how to put some numbers to it, sit down and shut up.
First off, basically any object that has kinetic energy will radiate heat as electromagnetic radiation, which light (electromagnetic radiation detectable to the human eye) comprises a small part of. This is what stems the original question and why color and heat are indeed related.
The actual answer is quite a bit more complicated than you think, for a few reasons.
1) Color is really only applicable to heat transfer through radiation. You will see most of your heat transfer in the engine compartment through conduction and convection, which means in most places it will make little to no difference.
2) Like was already mentioned, it also depends on how the part is colored. Different materials, and/or adding some sort of paint or powdercoating will also change heat transfer properties of the material (if you really want to dig into this, heat transfer coefficients are typically listed as "U factor" and are the inverse of the insulation factor "R" .
3) The optimum color for a certain part is not neccessarily intuitive. You'd have to know the properties of all the materials you're dealing with, and do some serious calculations to decide what would work best.
Purely speculation, but with very few exceptions do you see this actually applied anywhere (mass production or high end racing). I've seen some white NASCAR piston crowns, but that could have simply been a property of the coating used (the useful properties of ceramics don't neccessitate that they are white).
Summary
I'm not going to put all the work into finding properties and doing the math, but anyone else just wanting to laugh can feel free to try. I'll give the same general approximation that others did and tell you that it will be negligable, and even picking the optimum color for an application might be counter-intuitive to what you'd think. --

inverse of the insulation factor r.lol
so after all that you still dont have a definite answer.how about we just conclude that a white or black cai doesnt f'n matter/ --

Actually I said I wasn't going to do the math, not that I can't. You simply have no business posting in here. --

Sorry guys, I didn't mean to start a fight! Just trying to get all I can out of my LT1 engine, since it prefers colder temps. for more H.P.
Thanks for everyones input.
