Two-piece racing intake manifold. This genius system allows 2 different size rubbers to be fitted, to allow the opening to match the relevant carb size. The rubber can also be rotated on the base plate and thus adjust the carb positioning. On rigid versions and larger carburettors it can also be that the carb needs to be mounted under tension in a tight space. This will help with such a scenario. Delivery contains: 24mm and 32mm intake rubbers
