BMW F40 M135i, F44 M235i, 128ti

The Eventuri F40 M135i and F44 M235i intake system represents a comprehensive engineering solution developed through extensive real-world testing and airflow simulation. Featuring patented Venturi housing technology, this system delivers superior airflow efficiency compared to traditional cone filter setups, allowing turbos to operate with reduced waste-gate duty cycles and improved throttle response.

The system engineers a direct airflow path that eliminates abrupt directional changes, enabling the turbo to function with measurably less drag while maintaining consistent intake air temperatures across most driving conditions.

Key Features:

• Patented carbon fiber Venturi housing invokes laminar flow conditions and accelerates airflow without turbulence
• Integrated Mass Air Flow sensor section optimized for smooth flow to turbo inlet tube
• Bespoke generation 2 dry filter engineered to shape and maintain aerodynamic airflow path
• Maximized carbon fiber sealed duct design utilizes all available engine bay space
• Direct airflow routing eliminates 90-degree direction changes found in OEM airbox design
• Flexible rubber edging provides thermal protection and engine movement accommodation

Performance Notes:

• 0.2 second acceleration reduction (60-130mph) validated through real-world testing
• Enables turbo operation at lower waste-gate duty cycles
• Enhanced throttle response across driving conditions

Includes:

• Carbon fiber Venturi housing with integrated MAF tube
• Bespoke high-flow generation 2 filter
• Carbon fiber sealed duct assembly
• Aluminium inlet cowls
• 2 x laser-cut stainless steel bracket work
• Installation hardware and guide
