This serves to protect the ECU, immobilizer, and digital instrumentation: on 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 to be replaced?\u003c\/strong\u003e\u003cbr\u003e\nTypical symptoms include difficult cold starting, unstable idle, acceleration gaps, and increased fuel consumption. When removed, you often see green oxidation on the internal contact, cracks in the rubber, or black discharge marks on the outer 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 characteristics: a 4 mm connection and a 5 kΩ resistor. A cap with a different resistance or no resistance will change the behavior of the ignition system and, on injected models, can cause disturbances to 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\/products\/piaggio-293845-cappuccio-candela-schermato-beverly-x9-nexus-et4","provider":"Moon Bike S.r.l.","version":"1.0","type":"link"}
