{"product_id":"platinum-series-forged-piston-set","title":"Platinum Series Forged Piston Set","description":"The Manley Performance Platinum Series piston set represents a premium upgrade for Subaru 2.5L EJ257 WRX STI engines. Constructed from domestic 2618 alloy forgings, these pistons are engineered for superior strength and performance under demanding conditions. They feature exacting standards for ring lands and grooves, which contributes to enhanced ring seal and ultimately, more power.\n\nThe design incorporates proven cam and barrel (skirt) profiles, balancing significant power generation with a gentle interaction against cylinder walls. Manley's unique fixturing process ensures ultimate squareness between the ring grooves and the piston skirt by allowing both operations in a single setup. This set includes premium Chrome Moly wrist pins for added durability.\n\nThis piston set is compatible with Subaru Impreza WRX STI models from 2004 to 2012, including specific trims like the WRX STI Limited (2007, 2011-2012) and the WRX STI Special Edition (2010).","brand":"Manley Performance","offers":[{"title":"Default Title","offer_id":52689000005944,"sku":"MAN612005C-4","price":658.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687438897.webp?v=1784900152","url":"https:\/\/store.motormia.co\/products\/platinum-series-forged-piston-set","provider":"MOTORMIA","version":"1.0","type":"link"}
