{"product_id":"original-foam-air-filter","title":"Original Foam Air Filter","description":"The Polini Original Air Filter is a high-efficiency replacement element engineered to optimize the air-fuel mixture in Piaggio Liberty 50cc 4T, 125 Leader, and 150 Leader series engines. By facilitating improved intake airflow compared to stock components, it helps boost overall engine performance.\n\nThe filter features a dual-layer polyurethane foam construction: an outer blue layer with a 60 PPI porosity for fine filtration and a black inner layer with a 30 PPI porosity for pre-filtration of coarser particles. This design ensures that large debris does not compromise the fine filtration layer, prolonging the filter's service life. The exterior surface is intentionally undulating to maximize airflow intake area while capturing significantly more dust.\n\nMeeting European EN779 G3-G4 efficiency standards, the filter provides over 90% weighted efficiency and retains more than 50% of 1-micron particles. For maximum dust retention, the element can be treated with specific foam filter oil. The unit is fully serviceable through washing and drying, allowing for multiple uses. Compatibility covers Liberty 50 4T 2V, Liberty 125 LE Leader, Liberty 125 S Euro 3 Leader M381M, and Liberty 125\/150 Leader models.","brand":"Polini","offers":[{"title":"Default Title","offer_id":52663288430904,"sku":"203.0136","price":7.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687525823.jpg?v=1784325651","url":"https:\/\/store.motormia.co\/products\/original-foam-air-filter","provider":"MOTORMIA","version":"1.0","type":"link"}
