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

The CTS Turbo intake system for the G2X BMW 230i, 330i and 430i with the B46 engine delivers improved airflow that raises horsepower, sharpens throttle response and adds turbo sound — all without triggering a check engine light. It swaps the restrictive factory airbox for a 6" velocity stack high-flow filter so the engine breathes easier, with a custom-fit heat shield keeping intake temps low by isolating the filter from engine-bay heat. Premium construction makes it a durable, bolt-on upgrade for any enthusiast.
