BMW 3 Series (G20/G21/G28) Front Mounted Open Cold Air Intake System with Reinforced Silicone Ducting | G2X Sedan and Touring M340i – B58 I6 3.0L Turbo (2019–Present)

Unlock the hidden power of your BMW 3 Series M340i 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.
