BMW 2 Series (G42) Full Aluminum Semi-Closed Cold Air Intake System | M240i – B58 3.0L Turbo (2021–Present)

Unleash the full potential of your BMW 2 Series M240i (G42) with our Full Aluminum Semi-Closed Cold Air Intake System, precision-engineered for the B58 3.0L turbocharged inline-six.

Crafted from lightweight, high-strength aluminum, this intake system is built to perform under high boost and heat conditions while adding a clean motorsport look under the hood. Aluminum construction resists heat soak better than plastic, ensuring a steady supply of cooler, denser air compared to the stock airbox.

Engineered as a semi-closed system, it strikes the perfect balance between unrestricted open-cone breathing and the protection of a sealed housing. By reusing the factory turbo inlet and connecting through a shorter reinforced hose, airflow is more direct and efficient, reducing turbulence while improving throttle response and turbo spool.

Performance benefits you’ll notice:

1. Sharper throttle response with reduced lag
2. Quicker turbo spool-up and stronger midrange torque
3. Horsepower gains that scale even higher with tuning
4. Cooler, more consistent intake temps for reliable power delivery

On top of measurable gains, this intake enhances the driving experience of the G42 with a deep induction growl, crisp turbo spool, and sharp blow-off acoustics — perfectly matching the M240i’s compact, sporty nature.
