{"product_id":"si-20-20-air-filter-kit-with-intake-horn","title":"SI 20\/20 Air Filter Kit with Intake Horn","description":"The Polini air filter kit (MPN 203.0153) is engineered as an upgrade for the original SI 20\/20 carburetor on Vespa scooters. This kit modifies the air intake system by incorporating an intake horn that attaches directly to the original carburetor. The primary goal of this design is to enhance the air-fuel flow during the intake stroke, leading to an increase in engine power output.\n\nConstructed with a washable sponge air filter, the kit features an aluminum flange and a polished aluminum intake horn. Polini Motori specifically developed this modification for scooters like the Vespa PX 125-150-200 and LML 2T models. By increasing the air passage and preventing turbulence, the system optimizes the engine's performance.","brand":"Polini","offers":[{"title":"Default Title","offer_id":52663288627512,"sku":"203.0153","price":48.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687525824.jpg?v=1784325651","url":"https:\/\/store.motormia.co\/products\/si-20-20-air-filter-kit-with-intake-horn","provider":"MOTORMIA","version":"1.0","type":"link"}
