Show original supplier description
Unlock maximum airflow and performance from your BMW’s B46/B48 engine with the CTS Turbo Cast Turbo Inlet Pipe. This upgrade is engineered as a direct replacement for the restrictive factory inlet, significantly enhancing airflow to the turbocharger. This allows your engine to breathe more freely, leading to increased horsepower, torque, and a quicker turbo spool for a sharper throttle response. Crafted from durable cast aluminum, the CTS Turbo inlet pipe provides superior strength and heat resistance compared to the original plastic components. Its enlarged diameter and smooth interior design effectively eliminate bottlenecks, maximizing turbocharger efficiency. In addition to performance gains, this inlet pipe allows for a more pronounced and aggressive induction sound. The precision casting provides an OEM+ finish, offering a factory-like appearance while delivering enhanced performance benefits. This pipe is specifically designed for B46/B48 F-Series models, including various 130i, 125i, 120i, 230i, 225i, 220i, 330i, 325i, 320i, 430i, 425i, and 420i configurations across F20, F21, F22, F23, F30, F34, F32, F33, and F36 chassis.
