Dinan's turbo inlet pipe, designed to fit the BMW B58 engines found in the 140i / 240i F2x and 340i / 440i F3x models, is a direct replacement for the original plastic pipe, aimed at optimizing the airflow from the intake to the turbocharger. Made from high quality carbon fiber, this inlet provides a 24% higher airflow compared to OEM and eliminates the original resonator, resulting in improved turbo response and charge sound.
