Designed as a direct drop-in replacement for your factory air box, the K&N filter features a state-of-the-art oiled cotton gauze media layered between aluminum wire mesh. This design dramatically improves airflow without sacrificing filtration, giving your N20 2.0L Turbo engine the breathing room it deserves. Whether you're daily driving or pushing the Sports Line to its limits, this filter provides exceptional engine protection while boosting throttle response.

• Perfect Fitment for Your 328i Sports Line: Direct replacement for BMW 3 Series 328i (2012-2016 F30 Sedan, F31 Wagon, F34 GT) with N20 2.0L Turbo engine. Also fits 320i, 428i, and 228i models.

• Increase Horsepower & Acceleration: High-flow design allows more air into the engine, resulting in 1-4 HP gains and improved throttle response .
