US Air Force 482nd Civil Engineering Squadron

Ok, I just got a mazda rx8 at Ft Huachuca. I like it but..... people say it's a bad car to get lots of problems with it. so i want to make it go fast. so i went to a web site rx8shope.com and looking at the cold air intakes but i have no idea which one is the best to use. OR even if it is going to do anything to the car?? so i just need some advise i found 3 cold air intakes for the mazda rx8. AEM, K&N short ram and injen short ram.
