{"product_id":"bmw-intake-manifold-with-dual-disa-valves","title":"BMW Intake Manifold with Dual DISA Valves","description":"The Genuine BMW Intake Manifold is a direct replacement for your BMW's air-fuel distribution system. This specific manifold utilizes two DISA valves to modulate airflow, directly impacting the engine's power output and throttle response. Failure, often indicated by cracks or holes, can result in critical vacuum leaks, leading to lean engine conditions and misfires, thus requiring a replacement.\n\nThis intake manifold is particularly noted as a popular upgrade for lower-power N52 engines, commonly referred to as a \"3-stage manifold.\" It is designed to extract more horsepower at any given RPM. Symptoms of a failing intake manifold include engine misfires, rough idle, coolant or vacuum leaks, and illumination of the Check Engine Light (CEL).\n\nThis specific manifold is often integrated into conversion kits designed to upgrade various 2006-2013 BMW N52 engines (including 128i, 325i, 328i, 525i, 528i, and Z4 3.0i models) to the higher-output N52B30H0 manifold. This upgrade allows these models to benefit from the more advanced 3-stage system previously found only in the 2006 330i, which featured electronic valves to optimize air distribution. The installation is described as a direct, bolt-on process, with noticeable power gains appearing around 3,500 RPM and improving significantly at higher RPMs.","brand":"ModBargains","offers":[{"title":"Default Title","offer_id":52689264214328,"sku":"11617559523","price":930.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687392826.jpg?v=1784904295","url":"https:\/\/store.motormia.co\/products\/bmw-intake-manifold-with-dual-disa-valves","provider":"MOTORMIA","version":"1.0","type":"link"}
