Bleh... looks like someone took a cheap set of ITB runners and slapped an airbox on. I'd go with the Victor-X instead of the plenum version, and TWMs instead of the ITB version.
TWM's setup is ~$2000, but it comes with a new set of injectors in any size you want, along with fuel rail and FPR., all in -6 fittings.
You can plainly see the quality difference.
