Intake Manifold with Dual DISA Valves

The Genuine BMW Intake Manifold is a direct replacement for various BMW models, including the 128i, 328i, 330i, 530i, and Z4. This manifold distributes the air-fuel mixture to the engine's cylinders and features two DISA valves to manage airflow, directly impacting power and throttle response. Failure of the intake manifold can manifest as engine misfires, rough idling due to uneven air delivery, or coolant/vacuum leaks from cracks or bad gaskets. These issues often trigger a Check Engine Light (CEL). This specific manifold is also recognized as a 3-stage manifold and is a popular upgrade for lower-power N52 engines to enhance performance. It is a Genuine BMW part, ensuring it meets the stringent standards set by the manufacturer and is the same quality as original equipment. Fitment includes specific models such as the 2006-2013 BMW 328i (3.0L L6 Gas), 2006-2011 BMW 128i (3.0L L6 Gas), and various 330i, 330xi, 530i, 530xi, and Z4 models with 3.0L L6 N52 or N51 engines. Note that some 2006 models may also use part number 11617559530.
