All internally connected perfectly with 70mm butterfly connection.
It is necessary to receive your original manifold in advance in order to modify it and connect it so that the enlarged throttle is actually applied so that the flange is applied so as to have a larger passage surface.
Butterfly and flange not included.
Our modification already has the correct position for Lancia Delta, Coupe and Delta engine applications on Punto GT body to make the accelerator cable work well and correct position already oriented.
