Twin Carburettor Manifold Suit 1-1/4″ SU
Made in UK
Cast alloy type, this intake manifold for twin SU’s (H2, HS2 or H4 — NOT HS4) It has been carefully produced to minimize cross-port-flow interference caused by the balance tube and has generous radii in all the right places.
Further blending can be done if required, but leave a ground finish to promote fuel atomization. Do NOT polish!
