Turblown 20B 3 rotor upper intake manifold - pre order

We are dyno testing our first prototype early next month, once dyno confirms results, we wills start mold and sample production( 45 days). Early pre orders will then ship, full production will take an additional 50 days. 

This unit features the OEM 20B throttle body bolt pattern, but internally configured for an 87mm ford performance single plate throttle body. Any 20B throttle body adapter plate can be used, just could require slight porting depending upon throttle body size selected. There enough enough material to handle a 100mm TB body. OEM throttle body will require some port port to match properly. 

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 to match properly. 

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.
