Cold Air Intakes

What are some of the best intakes I can get that will give me the most out of the cold air intake

None of them. The stock intake is quite good. Even the ST200 when I was looking at other people's data showed an increase in intake temps over the stock airbox. This could have been due to some other issue such as improper secondary hose routing, but seriously the stock air box is quite good at getting cool air into the engine.

On top of that, most aftermarket "cold" air intakes require the installation of an oiled gauze type filter element. Testing has shown these to allow quite a bit of dirt through. Personally, I'm about keeping as much crud out as possible. Paper element filters when properly sized flow more than enough air even in a forced induction setup and give you far better filtration than oiled gauze. And they're not expensive so the reusability of the oiled gauze elements shouldn't even factor in.

Here's ISO testing data on oiled gauze elements, namely K&N, but for the most part all the oiled gauze and oiled foam filters do about the same.

I'm sold on the mountune unit as it draws it's air from the fender well rather than from the engine compartment.
ANY that draw from the engine compartment will be sucking in hot air after the car is warmed up, defeating the purpose.

But this one looks really neat .. again drawing air from outside the engine area

But would this fit an american car?

cheapest you can find and whatever look you are wanting for the engine bay
the stock / ST200 & mountune box (same thing ST200 is cheaper) will restrict power above 300whp
if you don't plan to upgrade your turbo at some point add an ITG panel filter to your stock box, there is zero gain going to a ST200 or mountune box

upgrade your intercooler, charge air temp where its at, don't worry about intake air temps from a "hot air intake"
