{"product_id":"forged-piston-set-81-25mm-bore","title":"Forged Piston Set, 81.25mm Bore","description":"The Toda Racing High Compression Forged Piston Kit is a set of high-performance forged pistons engineered to improve output in Honda B16A, B16B, and B18C engines. These pistons feature an 81.25mm bore and are designed to increase both displacement and compression ratio. The kit includes 4x forged pistons along with rings, pins, and clips.\n\nTechnical specifications vary by engine application, with reference compression ratios reaching up to 12.4:1 for the B18C. Crown volume and projection height measurements are specific to each engine type. Because these compression ratios are provided as a guide, precise measurements during assembly are required for proper setup.\n\nCompatibility is based on the manufacturer's JDM specifications. Please note that the manufacturer does not guarantee fitment for non-JDM markets, and users are advised to conduct independent research regarding compatibility with specific regional models. After-sale support does not include installation guidance, and professional assembly is recommended.","brand":"Toda Racing","offers":[{"title":"Default Title","offer_id":52664000643384,"sku":"13020-B16-000","price":749.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687729383.jpg?v=1784331688","url":"https:\/\/store.motormia.co\/products\/forged-piston-set-81-25mm-bore","provider":"MOTORMIA","version":"1.0","type":"link"}
