BMW G-series B46 Intake System for 230i/330i/430i

CTS Turbo Intake System, specifically designed for the G2X 230i, 330i, and 430i models equipped with the B46 engine. Delivering improved airflow, this intake system increases horsepower, sharpens throttle response, and enhances turbo sound—all without triggering a Check Engine Light (CEL).

By replacing the restrictive factory airbox with our 6" Velocity stack high-flow air filter ensures your engine breathes easier, resulting in better power output and smoother acceleration. A custom-fit heat shield keeps intake temperatures low by preventing engine heat from affecting the air entering the turbo. The premium construction ensures long-lasting performance, making this intake system a must-have for any enthusiast.
