Aftermarket intake manifold

Choose an aftermarket inlet manifold to fit SUs, Webers and other sidedrafts, as well as alternative manifolds for the stock carburetors.

Overview

• Aftermarket manifold finish quality can be really poor so check for flat flanges, port overlap. See Jason's Weber page

• Weber DCOE type manifolds are used by Dellorto DHLA and Mikuni/Solex PHH series

• Hitachi sidedrafts can use SU manifolds, but there are two-bolt diagonal pattern and four-bolt pattern manifolds

• Buy a complete kit — unless you like scrounging for all the little parts
