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.\u003c\/p\u003e\u003ch3\u003eConstruction\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Layer:\u003c\/strong\u003e Black open-cell polyurethane foam, 30 ppi — coarse pre-filter for large particles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Layer:\u003c\/strong\u003e Blue open-cell polyurethane foam, 60 ppi — fine filtration for microscopic dust\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond:\u003c\/strong\u003e Hot-formed process — layers joined without altering filtering properties\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Self-extinguishing polyurethane foam\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFeatures\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDual-Layer Construction — Outer Black 30 ppi Coarse Layer + Inner Blue 60 ppi Fine Layer\u003c\/li\u003e\n\u003cli\u003eSelf-Extinguishing Polyurethane Foam — Both Layers Open-Cell for High Airflow\u003c\/li\u003e\n\u003cli\u003eHot-Formed Bond — Layers Joined Without Altering Filtering Properties\u003c\/li\u003e\n\u003cli\u003eShaped to Fit Factory Airbox — No Modifications Required\u003c\/li\u003e\n\u003cli\u003eFits Vespa ET4 and Piaggio Leader 125\/150cc 4T Scooters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e 1300-1137\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Polini\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 8.5\" L x 7.5\" W x 1\" H\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eModel Fitment\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003ecc\u003c\/th\u003e\n\u003cth\u003eEngine Type\u003c\/th\u003e\n\u003cth\u003eYears\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eVespa ET4 Leader\u003c\/td\u003e\n\u003ctd\u003e125 \/ 150\u003c\/td\u003e\n\u003ctd\u003e4T AC (ZAPM19000)\u003c\/td\u003e\n\u003ctd\u003e2000–2005\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVespa ET4\u003c\/td\u003e\n\u003ctd\u003e50\u003c\/td\u003e\n\u003ctd\u003e4T AC (ZAPC260\/261)\u003c\/td\u003e\n\u003ctd\u003e1998–2002\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePiaggio Skipper ST\u003c\/td\u003e\n\u003ctd\u003e125\u003c\/td\u003e\n\u003ctd\u003e4T AC Leader\u003c\/td\u003e\n\u003ctd\u003e2000–2005\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePiaggio Skipper\u003c\/td\u003e\n\u003ctd\u003e150\u003c\/td\u003e\n\u003ctd\u003e4T AC (ZAPM2100)\u003c\/td\u003e\n\u003ctd\u003e2000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cp\u003e \u003c\/p\u003e","brand":"Polini","offers":[{"title":"Default Title","offer_id":67964637512001,"sku":"1300-1137","price":12.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/7785\/2225\/files\/az-p012-9679-0-1300-1137_4098e9b8-d422-44e3-ab33-dfc2b7041b22.jpg?v=1792558028","url":"https:\/\/azscooterparts.com\/products\/polini-air-filter-blue-vespa-150-et4-leader-engine","provider":"AZScooterParts","version":"1.0","type":"link"}
