Piaggio 8755250P Sponge Air Filter – Liberty 50, 125, 150, and 200 4T (1998-2023)

The Piaggio 8755250P air filter is the original foam filter element for the Liberty 4T airbox, across all displacements from 50 to 200 cc. This is the replacement part the manufacturer refers to in its catalog as "FILTER ELEMENT" and which Piaggio recommends checking at every service interval. When the foam is clogged with dust, the engine cannot breathe properly: fuel does not burn completely, the idle becomes erratic, acceleration flattens out, and fuel consumption increases – often without any warning lights appearing. On a small displacement four-stroke engine, the effect is immediate and noticeable: changing the filter is the most economical way to make the scooter feel like new, and it should be done even when it "still looks good," because fine dirt is not visible to the naked eye.

Frequently asked questions

What is the Piaggio 8755250P air filter?
It is the foam filter element for the Piaggio Liberty four-stroke airbox, referred to in the catalog as "filter element". It traps dust and particles before they enter the engine and is the original replacement part specified by the manufacturer for 50, 125, 150, and 200 cc displacements.

Which Liberty models does it fit?
It fits the entire 4-stroke Liberty family: from historical catalog models 1998-2005 like Liberty 125 Leader and 150 Leader, up to recent series like Liberty 125 iGet Corporate E5 from 2021-2023, including Sport, RST, Delivery, MOC, PTT, Poste, and Corporate versions.

How often should the air filter be replaced?
Follow the service interval indicated in your Liberty's owner's manual. If you ride many kilometers in the city, on dusty roads, or in winter, it is advisable to replace it sooner: the foam gets clogged more quickly, and a dirty filter increases fuel consumption and reduces acceleration well before showing obvious symptoms.

Can it be washed instead of replaced?
Light cleaning might help somewhat, but it should not be done with gasoline or aggressive solvents, which will damage the foam. The foam also ages on its own, losing elasticity and filtering capacity: given the cost of the replacement part, replacing it is always the best choice.

Is it also suitable for 2-stroke Liberty models?
No. This code is for the filter element of 4-stroke Liberty models. 2-stroke models use a filter with a different code: before ordering, verify the displacement, engine type, and year of your vehicle, or send us the chassis number and we will check it for you.
