It is also the spark plug to keep as a spare under the seat, because the same code fits almost the entire Piaggio, Vespa, Gilera, and Aprilia four-stroke range from 50cc to 250cc, and it does not expire in the drawer.\u003c\/p\u003e  \u003cdiv style=\"background:#f0f7f0;border-left:4px solid #28a745;padding:14px;margin:20px 0;border-radius:4px;\"\u003e \u003cstrong\u003e🛡️ Warranty and quality – Moon Bike S.r.l.\u003c\/strong\u003e\u003cbr\u003e Original Piaggio spare part, new and never fitted.

For two-stroke engines — Zip 2T, NRG, Typhoon 2T, Runner 2T — the catalog specifies a different spark plug with a different thermal rating.

Champion also lists it with the OE number 092. The corresponding Piaggio code is 438027.\u003c\/p\u003e \u003cp style=\"font-size:15px;\"\u003e\u003cstrong\u003eCan I fit an equivalent NGK?\u003c\/strong\u003e\u003cbr\u003e Conversion tables indicate the NGK CR9E as the equivalent of the Champion RG4HC. It is an \u003cstrong\u003eindicative correspondence\u003c\/strong\u003e: for your engine, the manufacturer's specified spark plug remains the 438027, and for a part that costs a few euros, it is better to stick with the original.\u003c\/p\u003e \u003cp style=\"font-size:15px;\"\u003e\u003cstrong\u003eHow many spark plugs do I need and what wrench should I use?\u003c\/strong\u003e\u003cbr\u003e Only one: all the engines in the table are single-cylinder. The price indicated refers to a single piece. To remove and replace it, you need a 16 mm spark plug wrench; work with a cold engine and tighten without overdoing it, because it has a flat seat with a gasket.\u003c\/p\u003e \u003c\/div\u003e\u003cp style=\"font-size:15px;\"\u003e\u003cstrong\u003eHow often should the spark plug be changed?\u003c\/strong\u003e\u003cbr\u003e Follow the maintenance schedule in your scooter's manual. In practice, it is best to remove and inspect it at every service: the color of the insulator and the condition of the electrode immediately indicate how the fuel mixture is burning, and replacing it costs less than any diagnostic test.\u003c\/p\u003e ","brand":"Piaggio","offers":[{"title":"Default Title","offer_id":58816031228252,"sku":"438027","price":10.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0966\/3660\/0668\/files\/piaggio-438027-candela-champion-rg4hc-scooter-4t.png?v=1787744447","url":"https:\/\/www.moonbikesrl.it\/en-us\/products\/piaggio-438027-candela-champion-rg4hc-scooter-4t-50-250","provider":"Moon Bike S.r.l.","version":"1.0","type":"link"}
