      Im gonna say what has been said a million times:
      Your not gonna get anymore performance than the stock box no matter what you do. Your best bet is a K&N panel filter in you airbox
      Oh really?

              brand doesn't matter, it's all marketing crap, you lose power with it anyway without a heatshield. so why spend 50+ dollars.

                  With the airbox assembly attached to the unit, the vacuum reading is in the 5" range.
                  ...
                  The AFM itself is responsible for most of the flow restriction - without the box in place, the pressure drop across the AFM & intake horn is 4.2"
