Intake manifold -101 OCTANE- 21mm unrestricted - for Piaggio 50-80 2T

A very cheap intake manifold for throttling the intake path. The passage is increased to 21mm. This component is mandatory when using a larger carburetor.

But even with original carburetors, the intake manifold already increases acceleration. Therefore also useful as a spare part if your original part already shows cracks and is porous. Which is not uncommon.
