You might as well call that a hot air intake and say goodbye to some horsepower because those kits allow the intake to pull from the very hot engine compartment.
That wasn't exactly the point. We all know that stock air is cold air but it is very restrictive the way it comes from the factory, cold air refers to opening the intake to allow more air to get in quicker. The cold air systems come supplied with an open box to seperate the engine heat from the intake. In my case I made my own. In addition to the intake you also need less restrictive exhaust which I mentioned. My HP did just fine. I'm making 310 which is up from 256 with that and softronic tune.
