This is for you guys that want to ditch that old factory style intakes and go with a better flowing and better designed intake. Overall volume of this intake is just over 2.7L and with the lower intake it's just over 3L. Available throttle body flange choices are, q45, factory z31/60mm 240sx, LS, and 5.0 mustang.
Vacuum block in the back is tapped for m10x1.25 and m8x1.25
These also don't clear factory fuel rails with out modifications, but do clear billet and aftermarket rails no problem.
