{"product_id":"cylinder-4-coolant-flow-upgrade-kit","title":"Cylinder 4 Coolant Flow Upgrade Kit","description":"The BLOX Racing Cylinder 4 Coolant Flow Upgrade Kit is engineered to enhance the cooling performance of Subaru EJ20 and EJ25 engines. Enthusiasts and tuners recognize that the factory design of the left-hand cylinder head can lead to higher temperatures in the #4 cylinder due to restricted coolant flow. This kit directly addresses this issue by increasing coolant circulation to this specific cylinder, drawing flow from the water pump.\n\nBy improving coolant distribution, this upgrade kit helps to mitigate the risks associated with overheating and detonation, contributing to a more stable and reliable engine operation, especially under demanding conditions.\n\nVehicle applications include the 2004-2020 Subaru STi, 2002-2014 Subaru WRX, 2005-2008 Subaru Forester XT, and 2004-2009 Subaru Legacy GT. Ensure compatibility with your specific vehicle year and model before purchase.","brand":"Blox","offers":[{"title":"Default Title","offer_id":52687157264696,"sku":"BXCC-50000-BLOX","price":80.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660187514.webp?v=1784880947","url":"https:\/\/store.motormia.co\/products\/cylinder-4-coolant-flow-upgrade-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
