Why not just move it to the trunk, use your factory tray and hold down, put a kill switch in line, and viola. Then you can use any intake and MAS you want.
IIRC my relocation kit was like $45 or $50, $20 for a breaker type kill switch, and $7.50 for some d-straps for the long run of power wire(the ones that come with the kit are plastic junk) . It really wasn't that big of a hassle, and looks clean and custom at the same time. Ah yeah, forgot to mention $4 for some terminal covers. You don't want something metal your carrying in your trunk being welded to your battery terminals.
