Casted Intake Manifold With Fuel Rail F90 M5 / F9X M8

LEVEL Performance intake manifolds with fuel rail for the BMW S63TU4 engine 

M5 F90, M8 F9X, X5M, X6M

Maximum Intake Efficiency

The LEVEL Engineering cast intake manifold for the BMW M5 F90 (S63) is engineered to maximize airflow, fueling precision, and thermal efficiency. It features an integrated secondary row of fuel injectors (MPI) along with dedicated ports for water-methanol injection (WMI).

The additional injector row enables true per-cylinder fueling, allowing for increased power output and improved fuel efficiency. Each manifold is equipped with four WMI injector ports to enhance intake charge cooling. This results in higher air density, reduced intake temperatures, minimized detonation risk, and additional power potential under high load.

Full OEM Compatibility

Designed as a true OEM-style replacement, the LEVEL Engineering intake manifold installs without any permanent modifications:

• Retains OEM throttle body and all factory sensor mounting points
• No engine bay modifications required
• Straightforward installation with no additional costs
• Proper wiring harness routing maintained to factory specifications

Advanced Engineering Development

This intake manifold is the product of extensive engineering analysis and real-world validation:

• 30+ MB of engine data logs used to establish accurate boundary conditions
• 15 GB of layered engine bay scans for precise fitment
• 70+ hours of reverse engineering the factory intake manifold
• 100 hours of machine analysis focused on OEM airflow efficiency
• 19,200 airflow optimization iterations
• 140 hours dedicated to final manufacturing-oriented design
• 54 hours of 3D-printed prototyping and physical test fitting

Performance Gains Over Stock

Comprehensive optimization delivers measurable improvements over the factory design:

• 42% reduction in pressure drop – Reduced airflow restriction improves throttle response and overall efficiency
• 31.58% increase in cylinder fill rate – Enhances combustion quality and supports higher power output

Material & Manufacturing

• Manufactured from A356.0-T6 cast aluminum, the manifold offers excellent strength, thermal stability, and long-term durability under extreme operating conditions.
• Weight: 4.5 kg / 9.9 lb
