{"product_id":"super-sqv4-blow-off-valve-kit","title":"Super SQV4 Blow Off Valve Kit","description":"The HKS Super SQV4 (Sequential Blow-Off Valve) employs a unique two-stage sequential valve structure with primary and secondary valves, managed by a differential pressure control system. This design allows for delicate pressure management across a wide operating range, from low to high boost.\n\nUnlike typical blow-off valves, the SQV4's \"relief-less operation system\" suppresses relief at high boost. This maximizes charge response during repeated boost and release cycles with throttle ON\/OFF. For the VR30DDTT engine, blow-off valves are placed on both banks to quickly release unnecessary boost pressure from each turbocharger, reducing their load when the throttle is off.\n\nThe kit includes dedicated 4-ply silicone hoses to replace the stock hoses between the turbocharger and intercooler, strengthening this section. All parts except the SQV4 main body are black to highlight the valve itself. The return hose uses a dedicated molded silicone hose, ensuring a snug fit in the engine bay.\n\nThis specific kit (71008-AN030V) is engineered for the 2023-2025 Nissan Z (RZ34) equipped with the VR30DDTT engine. Installation typically takes approximately 3 hours.","brand":"HKS Super","offers":[{"title":"Default Title","offer_id":52662768304440,"sku":"71008-AN030","price":1540.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663692350.jpg?v=1784320746","url":"https:\/\/store.motormia.co\/products\/super-sqv4-blow-off-valve-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
