High-Flow Aluminum Intake Design

The MBS B9/B9.5 Cold Air Intake System features silicone piping designed to provide a smoother, less restrictive airflow path compared to the factory intake system.

The combination of upgraded intake piping and a high-flow filter helps improve airflow efficiency while producing more noticeable turbocharger induction sounds.

Enhanced Turbo Sounds & Performance

One of the most noticeable benefits of the MBS intake system is the improvement in turbocharger sound.

The open-filter design allows you to hear more of the turbo spool and intake characteristics during acceleration, creating a more engaging driving experience without modifying the exhaust system.

By reducing intake restrictions, the system also helps support improved airflow and throttle response, particularly on vehicles running increased boost pressure.
