RevDop Intake System for BMW E8x/E9x Diesel – N47, N57 & M57

Maximize the fluid dynamic efficiency of your BMW diesel engine. With our bionically designed air filter housing for BMW M57, N57, and N47 engines, we fundamentally optimize airflow. Engineered for BMW E-Series models, our system reduces pressure loss by up to 17% compared to the stock component.

The result of this fluid-mechanical revision is a significantly improved flow rate and more precise throttle response under load – the ideal technical foundation for demanding performance applications.

Technical Highlights:

• Resistance Reduction: Bionically inspired internal geometry targetedly improves airflow. Turbulence is minimized, allowing the turbocharger to operate with less resistance.
• Variable Setup: The housing features an integrated configuration option:
• Open System: Focus on technical acoustics and maximum throughput.
• Closed System (closing flap included): Linearly guided airflow for maximum flow efficiency.
• Optimized Feedback: Homogeneous inflow relieves the compressor and improves high-RPM characteristics during dynamic load states.
• Precision Fitment: The component utilizes original mounting points for seamless technical integration.

Bionics & Engineering:

Unlike conventional systems, this housing was developed using modern flow analysis. The geometry is based on organic flow forms, effectively reducing abrupt cross-sectional changes and flow separation inside. This ensures uniform airflow to the turbocharger and optimized overall efficiency of the intake tract.

Material & Durability:

Manufactured from high-quality, thermally stable polyurethane, the housing is resistant to oil, fuel vapors, and heat – designed for maximum longevity under high thermal stress.

Area of Application:

This component is designed for international export and for use in motorsports. It serves as a technical upgrade for performance setups outside of public road traffic.
