Cold air intake do not cause valve damage. I have read several article and none of them metion valve damage. But CAI may cause hydro-lock cause engine damage. CAI use cold air molecules which are less dense. Being that they are less dense their structure can break down quicker and cover more surfuce area of the piston. CAI mainly have a power peak 5K rpm range. But being that CAI are longer they tend to bring air in slower. Your engine tends to not like working for its air. So as you can see CAI has advantages and dis-advantage. Short ram bring air in quicker, but because the air is warm being that the short ram is inside engine bay it air is very hot. For more info on air intake check out some article on team-integra website.

 

OK, what is your point? A search on this topic will easily tell you everything you just stated.

I'm not trying to be a bitch, but I don't understand why you keep starting these threads when the topic has been covered more than enough times to come up with tons of useful search results.

 

Dude.... you're wrong. Go reread what you saw.
1- molecules of colder air packed more densley than those of warm air.... thus you get more 02 molecules into your engine per cubic meter that is drawn through the filter resulting in greater efficiency.
2 - the velocity of the air in the tube has nothing to do with the simple length of the tube as opposed to the shape of the tube, and the harmonics that accompany the lay out. A shitty CAI will get less gains because it can't draw the air in as fast as a high quality and tested CAI even if the high quality CAI is longer. Aside from that the properties of fluid transfer say that the same vacuum applied to the ends of 2 pipes with the same cross sectional area will generate the same velocity of air travel throughout the pipe once the entire pipe has moving air particles flowing through it regardless of overall pipe lengths. Go check your sources.

actually, cold air molecules are MORE dense, hence the extra horsepower.
