Twin Carburettor Manifold Suit 1-1/2″ SU
Can be modified to suit 1-3/4″ SU
Made in UK
Cast alloy type, Fits either twin HS4 or HS6 (requires modification to fit HS6. 2 extra studs per carb) This intake manifold for twin SUs 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!
