{"product_id":"2618-alloy-piston-and-ring-set-for-b18c-engines","title":"2618 Alloy Piston and Ring Set for B18C Engines","description":"The Nippon Racing PS-P72-X is a comprehensive 4-piece piston and piston ring kit designed for Honda B18C4, B18C1, and GSR engines. A rigorous 6-step heat treatment ensures a piston that is as hard as many forged pistons but with significantly lower expansion rates.\n\nEach kit includes pistons, rings, locks, and wrist pins, providing everything needed for a complete engine rebuild. The pistons are precision-matched for wrist pin center to dome height and dome displacement, resulting in near-identical cylinder compression for improved horsepower and efficiency.\n\nAvailable in multiple sizes (81.0mm, 81.25mm, 81.5mm, 81.75mm, and 82.0mm), these pistons offer a solution for various engine builds.","brand":"Nippon Racing","offers":[{"title":"Default Title","offer_id":52663110795576,"sku":"PS-P72-X","price":323.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687515275.jpg?v=1784323922","url":"https:\/\/store.motormia.co\/products\/2618-alloy-piston-and-ring-set-for-b18c-engines","provider":"MOTORMIA","version":"1.0","type":"link"}
