{"product_id":"dry-sleeve-set-for-subaru-ej25-wrx-sti","title":"Dry Sleeve Set for Subaru EJ25 WRX STi","description":"The Darton DAR300-031-3D is a set of four dry sleeves engineered for Subaru EJ25 WRX and STi engines, offering a robust solution for enhanced engine durability and power handling. The 'Dry Sleeve' design eliminates coolant passages in the top flange, resulting in a more rigid structure that resists warping and sleeve expansion, crucial for high-performance applications.\n\nConstructed from centrifugally cast nodular iron, Darton sleeves are known for their exceptional strength and durability. The unique casting process ensures a tough bore finish that promotes a quick and complete piston ring seal for optimal combustion. The product specifications include a bore of 3.890 inches, an OD of 4.250 inches, and a wall thickness of 0.180 inches, with a flange thickness of 0.500 inches and a flange diameter of 4.600 inches. The application range for these sleeves is for EJ25 engines with bores from 99.5mm to 102mm.\n\nIt is critical to note that Darton cylinder sleeves must be professionally finished and honed at a machine shop to precisely match the specifications of the pistons being installed. This ensures proper fitment and performance. The sleeves are sold as a set of four.\n\nThis product is specifically designed for the following vehicles: 2006-2014 Subaru WRX EJ25 and 2004-2020 Subaru STi EJ25.","brand":"Darton","offers":[{"title":"Default Title","offer_id":52687608545592,"sku":"DAR300-031-3D","price":507.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662653493.jpg?v=1784885585","url":"https:\/\/store.motormia.co\/products\/dry-sleeve-set-for-subaru-ej25-wrx-sti","provider":"MOTORMIA","version":"1.0","type":"link"}
