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

Replace or upgrade your air filter with this Polini Dual-Layer Foam Air Filter for Vespa ET4 and Piaggio Leader 125/150cc scooters. Two-layer self-extinguishing polyurethane foam construction bonded by Polini’s hot-forming process, which joins the layers without compromising filtering properties. The outer black coarse layer (open-cell foam, 30 ppi) captures larger dust particles; the inner blue fine layer (open-cell foam, 60 ppi) with the Polini logo traps microscopic particles that cause the most engine wear. Shaped to fit the factory airbox — no modifications required.
