The BMW G20 320i/ 330i B48 Armaspeed intake is made with fine carbon fiber and has been developed to provide the most efficient and direct airflow path to the turbo while maintaining low inlet temperatures. It not only brings you a visual shock but also brings out the best efficiency in your car.
This particular G20 320i/ 330i B48 intake generates horsepower and delivers a plethora of turbo noises, previously hidden with the OEM intake. You'll hear the turbo spool, vent, and flutter under load, especially in a higher gear with a light push and release on the gas pedal.
