I recently purchased a 08 mega cab dually, I am wanting to put an air intake on, but I dont want to throw any any codes, which one is everyone leaning toward, I had a AFE on my 05 that I traded in and I loved it, any help would be great.

I put an afe stage2 w/pg7 on mine and love it. No diff. in mpg's though.

 

I used the Airaid and love it. Nice sound and an easy install.
