Isnt the air that travels though the intake tube moving quick enough to not really be effected by the temp of the tube reguardless of the material it is made of. Im sure there are some variables but nothing anyone will notice. Thats just my thought, please correct me if im wrong.

You might be right in that there wouldn't be much difference, however, *IF* all else were equal, why not just pick the material with lower thermal conductivity?
Of course there are other variables to consider, so the companies that use metals have chosen a higher thermal conductivity material for other reasons, for example:
Perhaps investing in several different $xx,000 molds to make plastic tubes is too expensive for a hot rodder with an idea to stick a filter on the end of a tube. It would be much easier and less expensive to go to his muffler shop friend to bend a metal tube and slap a filter on the end of it, an idea is born...the stainless steel intake system!
Perhaps they then made a couple prototypes and then they said, "Hey, let's polish or powder coat these metal tubes to make them look desireable and sell them to our friends".

Another important factor to consider is the velocity of air going into the engine...Velocity is impacted by inner wall surface, angle of bend in the tube, and intake openings at the filter...

Who cares about intake temp really? Of course, cooler air is nicer, but if the intake that is pulling in HOTTER air is making MORE power, than does air temp mean a darn thing really?
Arent we all looking for more power?, not bragging about how low our intake temps are?
Just seems inmaterial to me...

Maybe whomever I talked to is misinformed or is just out of the loop R & D wise, doknow. I don't remember his name either.
Cool though

As I stated in my earlier post inside this thread, I had previously posted quite a bit of information regarding the thermal properties of Stainless, Aluminum, and Polyethylene. haulin79 suggested a great link too. In fact, it was one that I used in an earlier post on this subject as well. The information is out there, you just have to find it.
All of the questions that keep getting asked (for the most part) have already been answered elsewhere in this forum. Check out the links below to learn more on the subject of cold air intakes, the difference in filter media being used, the importance on properly cleaning and oiling a filter, plus other useful info.
Remember - I'll answer as many questions as possible and always give a truthful answer, regardless if it shows a weakness in the S&B product line. If I don't respond to this forum quickly enough, anyone here can contact me directly as well.
Open Element Systems vs Closed Element Systems
Open Element Systems vs Closed Element Systems PT2
Quick facts on measuring actual air temp inside an intake
"Dry" or Non-oiled Air Filters
The Truth about Dyno Testing
Bottom of post talks about properly cleaning and oiling an air filter
Tuning an intake system by controlling air flow velocity and MAF readings
The easiest way to receive information about our current and/or upcoming products is to ask for me directly (Jay) when you call. In fact, you're more than welcome to email me directly as well. My address is located inside the post that I linked below. I'm trying to avoid the obvious spam associated with posting an email address on a forum, so you'll have to decipher the address. 
How to email me
I'm sure that this post will stir things up, but if you read all the posts I linked above and also search the internet to confirm the information, you'll find that I'm speaking the truth...and the truth is something that is badly missing in the cold air intake / air filter industry.
Cheers!

Obviously the heat under the hood is typically higher than that of the higher velocity air traveling through the intake pipe so do we want dissipation between the two temp. differentials or insulation? Somebody here was relating good intake construction material to heat sink material because of its good heat displacement benefits. Who wants that? Do we want the intake air to match that of the engine comparptment as Soon As Possible? Negative. What else is there to dissipate than the heat from the engine into the tube through some super heat conductor (like heat sink aluminum) Or do you want to dissipate the cool air into the warmer environment??? Either way it's counter-productive to what CAIs are advertised to achieve. Insulation, insulation, insulation is what you should be spending your energy on.
But again, we're only talking MINUTE differences.

When your piston rides down, air goes into the void. The higher the pressure in your intake manifold, the higher the pressure will be in your cylinders. It's that simple. Kinda....

you said velocity isn't important to horsepower as quantity-who on God's green earth told you that-
