intake manifold Top Performances 24mm for Minarelli AM

24mm intake manifold for maximum flow and performance increase when using a larger carburetor. When using a tuning intake manifold, please ensure that the opening matches the size of the carburetor. Too large or too small can hinder or slow the gas flow. As a general rule, misalignments of more than 2mm should be avoided. The ideal solution would be a 24mm opening to a 24mm carb for example.
