N52 Intake Manifold

The Genuine BMW 3-stage intake manifold is engineered to upgrade N52 engines, offering a direct bolt-on solution for increased high-RPM horsepower. While lower-output N52 engines feature a two-stage manifold optimized for low and mid-range torque, this 330i-spec manifold adds an additional pathway for directing more air, thereby boosting performance at higher RPMs without sacrificing low-end torque. This intake manifold directly replaces the stock unit and is compatible with a wide range of BMW models equipped with the N52 engine, including the 2006+ 128i, 325i, 328i, 330i, 528i, X3 30i, X5 30i, and Z4 30i. The system relies on two DISA (Differential Air Control) electric valves to manage airflow. It is important to note that while this intake manifold is a direct fit, it does not come with the required DISA valves or the associated software tuning. These components must be acquired separately to achieve the full performance benefits. For owners of SULEV models with the N51 engine, it is important to note that these already feature a 3-stage manifold, though they are de-tuned via software. To fully realize the power potential of this upgraded manifold on non-330i models, BimmerWorld recommends pairing it with their Stage 2 Performance Software. This software is specifically tuned to take advantage of the increased airflow at higher RPMs, enabling a significant horsepower gain – potentially up to 40hp over stock configurations.
