Turblown 20B 3 rotor upper intake manifold

New product under development, ETA 4+ months 

This unit features an 87mm Ford single plate throttle body. 

Fits both the OEM lower,GZ lower, and the Turblown 20B LIM( both side and semi pport )

OEM lower will require 1-2mm port work to match the primary runner size. 

Unlike the OEM upper intake manifold, all runners on this unit feature equal air distribution. The OEM upper favors rotor #2 by up to 5%.  Larger plenum size, and staged runner length features are designed for maximum power increase, throughout the entire rev range.
