Polini Dual-Layer Foam Air Filter for Vespa ET4 50/125/150

Polini Dual-Layer Foam Air Filter for Vespa ET4 50/125/150

This Polini dual-layer foam air filter is made for Vespa ET4 and Piaggio Leader scooters. It takes the place of the factory air filter, giving the engine clean airflow and filtration. Like many Vespa scooter parts, it sits right where the original filter was, so swapping it in is simple and keeps your scooter running as it should.

Construction Details

The filter has two foam layers made from self-extinguishing polyurethane. The outer layer is a coarse black foam that catches larger dust particles, and the inner blue layer is a fine foam that holds very small debris. Polini's hot-forming process bonds the two layers together firmly, and the filtering performance is kept intact.

Fitting Information

The filter is shaped to sit inside the factory airbox, so no modifications are needed during installation. It creates a tight seal that stops unfiltered air from reaching the engine, which helps cut down on wear and supports a longer engine life.
