So I'm trying to find a good intake for my stock g35 , any good suggestions ???

 

Rev-up intake airbox from a 2005-2007 6MT coupe, or 2005-2006 6MT sedan. "z-tube" from a 350Z

And for the future, this has been answered probably more than a thousand times. Strongly suggest using the search feature with the added "google search" box checked. Alternatively just type your search into your favorite search engine with the G35DRIVER tag added to it.
