Standard intake manifold for carburettor sizes up to 21 mm. The intake manifold is ideal as an inexpensive replacement part.
Often intake manifolds become porous over time and get cracks, which in turn lead to secondary air in the intake system. Restless engine running and loss of power are the result. In the worst case, the emaciation of the mixture can lead to piston eaters. Replacement is therefore mandatory as soon as cracks form in the intake manifold or it becomes porous.
