Description
The CTS Turbo Cast Turbo Inlet Pipe for BMW B46 and B48 engines is designed to unlock maximum airflow and performance by replacing the restrictive factory plastic inlet. This direct-fit upgrade improves airflow to the turbocharger, allowing the engine to breathe more efficiently and operate at its full potential.
Manufactured from high-quality cast aluminum, this inlet pipe delivers superior durability, heat resistance, and precise OEM-style fitment compared to factory plastic components. The enlarged internal diameter and smooth interior surface reduce airflow restriction, resulting in increased horsepower, improved torque delivery, and faster turbo spool.
Whether used with a factory intake or an upgraded aftermarket system, the CTS Turbo inlet pipe enhances overall efficiency, throttle response, and turbocharger performance while maintaining a clean OEM+ appearance. The upgraded design also allows for a more pronounced and aggressive induction sound under acceleration.
