BMW G20 Sedan / G21 Touring 3 Series Sedan Semi-Closed Cold Air Intake System w/ Heat Shield & Ducting | 2.0L B48 Engine - 320i 330i (2019+)

Unleash the true performance of your BMW 320i or 330i with our Cold Air Intake System, designed to maximize airflow, reduce heat soak, and sharpen throttle response.

The BMW B48 2.0L turbocharged inline-4 powers models like the 320i and 330i and is known for its efficiency, reliability, and impressive tuning potential. While responsive from the factory, the restrictive OEM airbox holds back its full capability. Our upgraded cold air intake system replaces the stock setup with a high-flow filter, precision-fit heat shield, and high-temp silicone hose, allowing the B48 to breathe more freely for more consistent and responsive power.

The semi-closed design gives the best of both worlds — unrestricted airflow from the 360° filter while shielding against hot engine bay air. This ensures cooler, denser intake air, which translates into improved throttle response, stronger midrange torque, and more reliable performance, especially under tuned boost levels.

With a pre-cut MAF sensor slot and direct OEM mounting points, installation is hassle-free. Beyond the performance gains, the intake delivers a deeper induction note, sharper turbo spool, and a satisfying blow-off sound, elevating your driving experience.
