Maximum Intake Efficiency
The cast intake manifold from LEVEL Engineering is designed for the BMW M5 F90 S63 and is equipped with a secondary row of fuel injectors (MPI), as well as ports for water-methanol injection (WMI). The additional row of injectors enables per-cylinder fuel injection, which increases engine power and improves fuel efficiency. Each manifold includes four WMI injector ports, enhancing fuel-air mixture cooling. This increases mixture density, reduces the risk of overheating and detonation, and contributes to additional power gains.

Full OEM Compatibility
One of the key advantages of this manifold is its direct replacement for the stock intake manifold without modifications.

Retains OEM throttle body and sensor mounting points
No modifications required to the engine bay
Quick and easy installation without extra costs
Allows proper wiring harness mounting according to factory specifications

Advanced Engineering Development
The development of the LEVEL Engineering intake manifold is the result of extensive technical research:

Over 30 MB of data logs collected for precise boundary condition settings
15 GB of layered scans of the engine bay for accurate fitment
More than 70 hours spent on reverse engineering the stock manifold
100 hours of machine time dedicated to analyzing OEM intake efficiency
19,200 optimization iterations for ideal airflow design
140 hours spent on final product design for manufacturing
54 hours used for 3D printing prototypes and real-world fitting tests

Superiority Over the Stock Design
Engineering optimizations have resulted in significant improvements:

42% Reduction in Pressure Drop -The optimized manifold shape reduces airflow resistance, improving engine response and efficiency
31.58% Increase in Cylinder Fill Rate - This enhancement leads to better combustion quality and increased power output

Material and Manufacturing Technology
The manifold is made from A356.0-T6 cast aluminum, ensuring high strength, heat resistance, and durability.
