Heat is not light. Light can emit/project heat but where is the light in lets say a chemical hand warmer? Heat, the kind we're talking about- not radiated energy but absorbed, is the excitement of molecules in an object & there are other forms of energy that can excite molecules into a heated frenzy besides light; electricity for one. What color something is only relates to heat within the light spectrum- pour gas all over a white teener & a black teener & I don't think the color will really matter. Put 2 teeners in the sun & the black one will be hotter than the white one, period. We can't see infrared or ultraviolet but how those particles impact onto a surface is still going to be measured within & outside of the visual light spectrum. Cut the light out & that range of heat is removed. As to weather or not flat black absorbs more non-visual heat over white is what did not make sense to me. Poor choice of words on my part before.

Get a"natural" industrial look on top of the motor, and efficient temp wise(?)... |

The runners are very short and the air RUSHING through them is rather quick so the short answer is "No, runner color doesn't make a difference". If the air had time to 'puddle' in the intake runner one may have a possible arguement.

NOT! do what you like, it won't affect a thing. there are ton's of things to worry about that will affect engine temps than the color of the intake runners |

If you think about it, in modern cars almost every intake manifold is flat black plastic. I doubt every auto maker in the world is that clueless...

again, heat and light are just two different words for the same thing.
electromagnetic radiation same thing, just different wavelength, frequency, amplitude and thus energy content. (IMG:style_emoticons/default/cool_shades.gif) Andy |

QUOTE(retrofit @ Jul 9 2007, 10:51 PM) Is there any evidence that painted EFI intake tubes will make the engine run hotter/cooler depending on the color? Over at 914 groups someone posted that when he painted his intake tubes black the engine ran 20* hotter. So if you paint the tubes a light color (reflective, not absorbing heat?) it will run the same or, cooler? I have seen nicely detailed engine bays where the plenum and intake was painted the body color. Could this be a functiional mistake?
