S58 Turbo Inlet Pipe is purpose-built to eliminate the airflow restrictions in your 2017-2021 Pre LCI BMW X3M and X4M. Designed specifically for the Pre LCI (Pre facelift) versions only, this upgrade replaces the factory plastic inlet with a high-flow CNC pipe that delivers smoother, faster airflow to your turbos. Expect sharper throttle response, faster spool, and stronger performance across the powerband—whether you’re stock or tuned.

BMW’s stock inlet system works—but it’s far from optimal. It features sharp bends, uneven internal surfaces, and a resonator that slows airflow. Our upgraded design corrects this with a straight-through, turbulence-free path, capable of handling the demands of both factory and hybrid turbo setups.

Unlike other aftermarket pipes, Our solution is engineered with full OEM compatibility in mind. It retains the factory PCV connection and sensor location, ensuring full ECU integration and a trouble-free install.

This is a true bolt-on part—no trimming, no guesswork.
