BMW 4 Series (G22/G23/G26) Front Mounted Open Cold Air Intake System with Reinforced Silicone Ducting | G2X Coupe, Convertible, Gran Coupe M440i – B58 I6 3.0L Turbo (2021–Present)

Unlock the hidden power of your BMW 4 Series G2X M440i with this Open Cold Air Intake System, engineered to maximize flow, enhance turbo sound, and deliver sharper throttle response across the B58 3.0L Turbo I6.

Built from high-temperature reinforced silicone, this system provides a smooth, unrestricted path for incoming air — dramatically reducing turbulence and pressure drop. The open-cone design increases the volume of cool air entering the turbo inlet, resulting in quicker spool, improved mid-range torque, and a satisfying induction growl under throttle.

This kit includes a high-flow cone air filter, turbo inlet, stainless steel band clamps, and pre-cut provisions for OEM sensors and ducting. Installation is straightforward and fully reversible, integrating seamlessly with factory mounting points for a clean, OEM-plus look under the hood.
