twin 4 barrel carb adapter to 142 manifold AS0139

AUD $425.00


Aussiespeed twin four barrel carb adapter will bolt to Aussiespeed super charger manifolds or weiand supercharger manifolds to fit 2×4 barrel carbs in either sideways mounting or front to back with single metering block carburetors.

The bolt on adapter will not accept 2x double pumpers when placed inline or carburetors with dual metering blocks. Another use is for fitting 2x LPG gas mixers.

In the earlier part of 2018 the adapter went through a redesign reducing the plenum area.
