Fits select 2019-2025 BMW 230i, 330i, and 430i models (L4-2.0L).

The AEM 21-879C Performance Air Intake System is designed to reduce intake restriction and allow your engine to breathe more efficiently than the factory airbox allows. This system has been tuned and dyno-tested to provide increases in horsepower and torque by delivering a higher volume of cooler oxygen-rich air to the engine.

The intake features a mandrel-bent aluminum tube finished in a durable gunmetal gray powder coating. To protect the intake charge from radiant engine bay heat, a custom-shaped heat shield and lid are included. Filtration is handled by an oversized, tapered cylindrical AEM Dryflow air filter. This oil-free synthetic media provides excellent airflow and filtration efficiency and can be used for up to 100,000 miles before cleaning is required, depending on driving conditions.
