I have been toying with the idea of adding a cold air intake to my FJ. I understand the concept of the cold air intake. However, when I looked at the engine compartment of my FJ, I noticed that it already had a CAI -- the engine draws air from a compartment isolated from the main engine allowing it to draw cooler air. Am I correct about that? If so, will an after market CAI improve on the stock CAI? Thanks for any expertise/wisdom you can send my way.
