This pair of H4 SU carburettors is correct for Austin Healey 100 BN1 and BN2 models. As per the original specification, these twin carbs were fitted to the 2660cc four-cylinder engine and remain the standard setup for early Big Healeys.
Each unit is built to match OE part number AUC718, offering reliable fuelling for owners maintaining stock configuration or refreshing an ageing setup. The throttle spindles, float chambers and jet assemblies reflect the period design and layout found on original cars.
Suitable for Austin Healey 100 BN1 and BN2 models using twin SU H4 carburettors.
To support long-term running, a H4 service kit is available for each carburettor. It includes the essential gaskets, seals and needle components needed for regular overhaul and adjustment.
