Unlock improved airflow, faster turbo response, and enhanced reliability with the MBS B48/B46 G-Series Turbo Inlet. Engineered as a direct replacement for the restrictive factory plastic turbo inlet, this high-quality aluminum upgrade eliminates a common weak point while allowing your turbocharger to breathe more efficiently.

The factory B46/B48 turbo inlet is prone to cracking and failure over time, particularly on tuned vehicles, due to its plastic construction. The MBS Turbo Inlet is manufactured from durable aluminum for superior strength and longevity, providing a permanent solution that outperforms the OEM component.

Featuring an enlarged, smooth-flowing internal design, the inlet reduces airflow restriction and turbulence, helping the turbo spool quicker while improving throttle response and supporting additional horsepower and torque when paired with other performance modifications. Whether your BMW is stock or modified, this is an excellent upgrade for both reliability and performance.
