BMW F10 / F11 5 Series Semi-Closed Cold Air Intake System w/ Heat Shield & Ducting | 2.0L N20 Engine - 520i 528i

Unleash the true performance of your BMW F10 / F11 5 Series with our Cold Air Intake System, designed to improve airflow, reduce heat soak, and sharpen throttle response.

The BMW N20 engine — a 2.0L turbocharged inline-4 — powers models like the 520i and 528i, and is well-known for its efficiency and tuning potential. While capable from the factory, the restrictive OEM airbox limits what the turbo can achieve. Our upgraded cold air intake system replaces the stock setup with a high-flow filter, precision-fit heat shield, and high-temp silicone hose, giving your N20 the airflow it needs for more responsive power.

The semi-closed design is the key. Unlike fully open intakes that pull in excess hot engine bay air, this system balances unrestricted airflow with effective heat shielding. The result is cooler, denser intake air, which improves midrange torque, throttle response, and consistency — especially under tuned boost levels.

With the addition of a pre-fit MAF sensor slot and OEM mounting points, installation is seamless. The system also enhances the driving experience with a sportier induction tone, sharper turbo spool, and a satisfying “whoosh” under throttle.
