BMS G Chassis B48 Aluminum Short Turbo Inlet | BMW
21st Aug 2026
Improve the turbocharger airflow system on your G Chassis BMW equipped with the Gen2 B48 engine with the Burger Motorsports (BMS) Aluminum Short Turbo Inlet Upgrade. Designed to replace the factory plastic turbo inlet, this high-flow aluminum component provides a smoother and more direct path for air traveling from the intake system to the turbocharger.
The factory inlet is engineered around OEM packaging requirements and incorporates restrictions and a sound resonator within the airflow path. The BMS short turbo inlet replaces that design with a smooth aluminum construction, helping reduce unnecessary restrictions and turbulence while providing a stronger and more performance-oriented solution for modified B48 applications.
High-Flow Aluminum Turbo Inlet
The BMS Aluminum Short Turbo Inlet is designed to optimize airflow between the intake system and turbocharger.
Its streamlined internal design helps reduce restrictions and turbulence compared with the factory-style inlet, allowing the turbocharger to draw air through a more direct and efficient path.
For B48 engines equipped with upgraded intake systems or additional performance modifications, improving the airflow path before the turbocharger can complement the vehicle's overall intake and turbocharging setup.
Durable Aluminum Construction
Unlike the factory plastic component, the BMS turbo inlet is manufactured from durable aluminum, providing a stronger alternative designed to withstand the demands of performance-oriented applications.
The inlet features a CNC-machined turbo fitting for precise assembly and a clean, secure connection. Combined with the supplied O-ring, C-clip, silicone coupler, and heavy-duty clamps, the kit is designed to provide a reliable connection throughout the intake system.
Removes the Factory Sound Resonator
One of the key design changes is the removal of the factory intake sound resonator.
By eliminating the resonator and simplifying the airflow path, the BMS short turbo inlet provides a more direct route toward the turbocharger. Removing this component can also allow more of the natural intake and turbocharger sound to be heard, adding a more noticeable character to the engine bay and cabin.
Designed for G Chassis B48 BMWs
The BMS short turbo inlet is specifically designed for compatible G Chassis BMW models equipped with Gen2 B48 engines.
It is available for applications including the G42 2 Series, G20/G21 3 Series, and G22/G23/G26 4 Series, with compatibility varying by engine and model configuration.
For optimal airflow performance, BMS recommends pairing the inlet with the BMS B48 Competition Air Intake.
