Product Details
DESCRIPTION: The Polini air filter sponges have two layers. The first layer has medium-sized pores to filter rough dust particles. The second layer has very small pores that can also filter dust particles of microscopically small size (it’s these that cause the most damage). The filters are made of self-extinguishing polyurethane foam.Their two layers are joined together utilizing a special hot-forming process that does not manipulate the filtering properties. The outer rough layer is made of black filter material: open polyurethane foam with a permeance of 30 ppi (pores per inch). The fine-pored second layer comes in blue filter material: open polyurethane foam with a permeance of 60 ppi (pores per inch).This product is intended as an OEM equivalent for listed models. Any misuse, alteration or alternative application is prohibited by law.FitmentModel / manufacturerccTypeEngineModel YearsPIAGGIO Skipper150ZAPM21004T AC’00PIAGGIO Skipper ST125LEADER4T AC’00-’05VESPA ET450ZAPC260 / ZAPC2614T AC’98-’02VESPA ET4 LEADER150ZAPM190004T AC’00-’05VESPA ET4 LEADER125ZAPM190004T AC’00-’05About Polini:For over 50 years,Polini has stood unparalleled in the racing and tuning scene.Polini has powered both off-road and road racing legends to multiple MXGP and MotoGP world championships including the legendary Valentino Rossi.Polini sets the standard for high-end tuning and top-quality performance components.Made in Italy

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.
