{"product_id":"86-00mm-bore-forged-piston-set-with-rings","title":"86.00mm Bore Forged Piston Set with Rings","description":"The Wossner K9062D100 forged pistons are engineered for high-performance applications in Mitsubishi Eclipse, Talon, and EVO 4-7 models utilizing the 4G63 engine. These pistons are crafted from dedicated, in-house produced forgings, ensuring superior strength, reduced weight, and optimal design for demanding engine conditions.\n\nFeaturing a bore size of 86.00mm and a compression ratio of 8.0:1, these pistons are designed to complement performance engine builds. Key design elements include specially developed valve pockets, intricate dome and crown shapes, and optimized skirt profiles. They also incorporate steel nitride\/napier xx rings for enhanced durability and sealing. The set is supplied complete with all necessary rings, wristpins, and retaining clips, along with detailed specification sheets.\n\nThese pistons offer a lower compression ratio (8.0:1) compared to the OEM specification (8.8:1), making them suitable for forced induction applications where lower compression is often required to prevent detonation. The 150mm rod length and 34.7mm compression height are also specified for compatibility with the 4G63 engine. The dome volume is -14.6cc, contributing to the reduced compression ratio.","brand":"Wossner","offers":[{"title":"Default Title","offer_id":52664139120952,"sku":"K9062D100","price":623.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687542221.jpg?v=1784333930","url":"https:\/\/store.motormia.co\/products\/86-00mm-bore-forged-piston-set-with-rings","provider":"MOTORMIA","version":"1.0","type":"link"}
