BMW B58 Gen 2 G-Series M340i/M440i/M240i Performance Air Intake

BMW B58 Gen 2 G-Series M340i/M440i/M240i Performance Air Intake

Unlock the full performance potential of your BMW B58 Gen 2 engine with this High-Performance Air Intake System, engineered to maximise airflow, improve turbocharger efficiency, and deliver sharper throttle response with an aggressive induction sound.

Designed specifically for BMW G-Series vehicles equipped with the Gen 2 B58 engine, this Performance Air Intake replaces the restrictive factory airbox with a high-flow intake system that allows the turbocharger to breathe more efficiently. The result is faster turbo spool, improved engine response, and increased airflow for both stock and modified vehicles.

Manufactured from premium materials and paired with a high-flow performance air filter, this intake system delivers exceptional filtration, durability, and long-term reliability while maintaining OEM-quality fitment. Whether your vehicle is completely stock or running Stage 1, Stage 2, ethanol blends, or an upgraded turbocharger, this intake is one of the most effective bolt-on upgrades for improving both performance and driving enjoyment.
