It serves to protect the ECU, immobilizer, and digital instrumentation: on fuel-injected vehicles, a cap without a resistor can cause electronic malfunctions.\u003c\/p\u003e\n\n\n\u003cp\u003e\u003cstrong\u003eHow do I know if the cap needs replacing?\u003c\/strong\u003e\u003cbr\u003e\nTypical symptoms include hard cold starts, unstable idling, hesitation during acceleration, and increased fuel consumption. Upon removing it, you often see green oxidation on the internal contact, cracks in the rubber, or blackish discharge traces on the external surface.\u003c\/p\u003e\n\n\n\u003cp\u003e\u003cstrong\u003eWhich scooters does it fit?\u003c\/strong\u003e\u003cbr\u003e\nThe official Piaggio catalog lists it for a very wide range: Piaggio Beverly, Carnaby, MP3, X7, X8, X9, and X Evo, Gilera Nexus, Runner 4T, and Fuoco 500, Aprilia Atlantic, Mojito, Sport City, and SR MAX, Scarabeo with Piaggio engine, and Vespa ET4 125 and 150.\u003c\/p\u003e\n\n\n\u003cp\u003e\u003cstrong\u003eCan I install a universal cap instead of the original?\u003c\/strong\u003e\u003cbr\u003e\nOnly if it has the same specifications: 4 mm connector and 5 kΩ resistance. A cap with different or no resistance changes the ignition system's behavior and, on fuel-injected models, can create interference with the onboard electronics.\u003c\/p\u003e\n\n\n\n\u003c\/div\u003e","brand":"Piaggio","offers":[{"title":"Default Title","offer_id":58523660419420,"sku":"293845","price":8.1,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0966\/3660\/0668\/files\/piaggio-293845-cappuccio-candela-schermato-beverly-x9-nexus.png?v=1785691292","url":"https:\/\/www.moonbikesrl.it\/en-eu\/products\/piaggio-293845-cappuccio-candela-schermato-beverly-x9-nexus-et4","provider":"Moon Bike S.r.l.","version":"1.0","type":"link"}
