This cast aluminium inlet manifold for twin SU H4 carburettors is a close reproduction of the original 12A661 (part number AEG347) casting but with a performance enhancing re-design. As used on the late 998, 970, 1070 and 1275 Mini Cooper and usually matched to the 12G295 cylinder head, the manifold can also be used with HS2 carburettors if the step up in bore size is deemed acceptable from carburettor to manifold.

 

Designed by our own CAD team, cast by our UK based partners and then CNC machined in house at SU Carburettors, you can be assured of the highest quality.

 

The carburettor mounting flanges are shaped specifically to match the H4 carburettor unlike some others which have been cast with a multi-use fitment in mind. The head side flange of the manifold is improved with more material to allow re-shaping of the inlet to match the head. No need to add extra material to the manifold with ugly welding and subsequent machining. The mounting flange is as per original Mini Cooper S, without the head stud alignment holes. This means if the manifold is opened out there are no concerns with mis-alignment as it can be fitted upwards or downwards to suit.

 

Crank case breather port is machined with blanking plug fitted, should it be required, and the throttle cable mounting location is machined ready to take the cable support. The underside of the balance pipe has a sculpted shape to help avoid interference with larger bore exhaust centre branches.

 

During design, special attention has been given to the internal cast shape of the manifold to closely reflect that of the original, which in terms of flow, is proven to perform exceptionally well with the SU H4 carburettor. 

 

Finally, your seal of approval, a machined SU logo tastefully finishes things off.
