I have a 2002 Ram 1/2 ton with the 5.9 liter v8. I'm fixing to put a cold air intake and new exhaust on and and was wondering what the best intake would be. I'm thinking about gettting the Airaid anybody have any input for me, is there a better brand.

 

Ask ten people this one and you are likely to get ten diffent brands.
This is my take on CAI's:
The stock resonator (the plastic box that sits on top/in front of the throttle body) is the biggest bottle neck in the intake system. So, any brand that is relatively straight through and replaces the resonator and uses a high quality filter will basically be a good setup.
