3-Stage Intake Manifold Assembly for N52 Engines

The BMW M Intake Manifold Upgrade Kit is designed to significantly enhance the performance of N52-powered vehicles. Originally featured on the E90 330i, this 3-stage manifold utilizes two DISA valves to precisely control air flow to the cylinders, which, when paired with ECU adjustments, can lead to substantial power gains. This manifold is a direct bolt-on upgrade for any N52 engine variant. The kit includes the 330i intake manifold itself, both necessary DISA valves, all required gaskets, mounting hardware, and a crankcase vent hose, providing a comprehensive solution for upgrading your engine's intake system. The primary benefit of installing this manifold, along with an ECU tune, is the potential for an increase of up to 42 horsepower, improving overall engine output and responsiveness. It's important to note that the necessary flash software is not currently available from ECS Tuning. This intake manifold is constructed from materials typical for engine components, such as aluminum, plastic, or composite materials, ensuring durability and efficient operation. The system's function relies on the precise movement of air, and any cracks or leaks in the manifold or its gaskets can lead to vacuum leaks, resulting in lean engine conditions, misfires, and a Check Engine Light. This upgrade is particularly popular for vehicles equipped with lower-output N52 engines seeking to achieve higher performance levels.
