Project R1 — Cold Air Intake System for BMW F3X B58 (M140i / M240i)

The Project R1 cold air intake system is engineered to unlock the full potential of BMW models equipped with the B58 3.0-liter turbocharged engine. The factory intake design includes internal partitions and a small Helmholtz chamber that introduce unnecessary turbulence and restrict airflow, limiting performance. Project R1 eliminates these inefficiencies to deliver improved airflow, response, and sound.

Key Benefits

Optimized Airflow Design
The custom intake pipe removes internal restrictions found in the OEM system and allows airflow to move smoothly and efficiently into the turbocharger. This reduces turbulence and increases the volume of cold air delivered to the engine.

Enhanced Intake Sound
By eliminating sound-dampening partitions in the stock system, the Project R1 intake reveals a deeper and more aggressive induction tone, giving the engine a more engaging sound character without excessive resonance.

Improved Throttle Response
More efficient airflow along the intake path improves throttle response and engine responsiveness under acceleration.

Technical Highlights

• Increased Filter Area — Larger filter surface for better airflow and filtration.
• 92 mm Intake Pipe — Oversized diameter reduces restriction and supports higher engine output.
• Closed Airbox with Cold Air Windows — Dedicated cold air intake sections in the housing minimize hot under-hood air.
• Improved Air Chamber Design — Larger, fully sealed air chamber reduces intake air temperature and shields airflow from engine heat.
• Optional Dynamic Air Scoop — Add a dedicated scoop to direct ram air into the intake for even cooler intake temperatures (sold separately).

Vehicle Compatibility

Compatible with a wide range of BMW models powered by the B58 engine, including:

• BMW F22 M140i / M140i xDrive
• BMW F22 M240i / M240i xDrive
