Les Leston carburettor stacks are vintage performance velocity stacks for carburettors, often associated with classic British sports cars like the TR2-4A and MGB. They are designed to improve airflow by smoothing the entry of air into the engine, which can increase power and create a distinct intake sound. These stacks are now considered a rare and desirable period part for collectors and enthusiasts.
