Just curious to what you guys thought ... I still wanna keep in quiet but max out the HP... thanks

 

keep the stock air box setup.

or setup make your own setup and try to re-locate the filter in the coolest place possible (I am refering to temperature when I say Cool).

 

or just a cone filter works nice.

 

I want to interject since the stock air box was a good intake for the 4th gens, it helped keep good low end, was decent at mid range and maybe struggling a little bit on high end, but with the VIAS from the 3.5 we know it will be able to breath much better on the high end, and mid range will see improvements as well.

I'd say rig back up the stock intake setup, or stock hybrid setup
