Intake manifold -MALOSSI- MHR- Piaggio 2T - Ø 28 / 22 - length 26.5mm angled

Among the main factors that influence volumetric performance are the frictional losses of the fluid in its passage from the inlet (air-fuel mixture) to the air filter to the combustion chamber.
Consequently, one of the factors influencing these losses is the intake manifold, as the mixture must flow through the inlet of the manifold with as little loss as possible.
For this reason, large diameter expansions and acute angles on the mixture flow path should be avoided.
The intake manifold also serves as a storage chamber for the newly injected mixture, as the mixture column moves at a certain speed and therefore needs a certain amount of time to stop when the inlet diaphragm closes.
The mixture collects in the intake manifold and presses against the diaphragm plates.
For this reason, each intake manifold is associated with a specific speed range within which maximum power is achieved.
The intake manifold also serves as a support for the carburettor by connecting it to the engine casing or cylinder.
Consequently, it serves to dampen, if necessary, the vibrations transmitted from the casing to the carburettor and thus avoid the phenomenon of emulsion of air and petrol in the float chamber.
This seemingly simple part therefore requires in-depth theoretical and practical studies to be used in the best possible way.
And this is what Malossi's technicians have achieved.
Thanks to many years of experience in engine supply systems, Malossi has created a new line of rubber and aluminum alloy intake manifolds for the new generation of scooters, tested and developed by the Malossi experience department both on the road and on the most important race tracks.
In particular, Malossi rubber intake manifolds have a multi-part structure: an aluminum insert which is then incorporated into a special oil and petrol resistant plastic material.
This ensures high rigidity of the fixing part on the housing and elasticity of the intake manifold.

ATTENTION: when fitting the MHR intake manifold, any adjacent plastic parts must be slightly adjusted.
