K&N roto-molded cold air intake for BMW 520i/528i N20 2.0L (2011–2017) increases airflow using a rotationally-molded HDPE tube and a washable, reusable high-flow oiled-cotton filter to boost horsepower and torque. The oversized conical filter allows extended service intervals under normal driving, a custom heat shield protects intake air, and typical installation takes under an hour; the system is backed by K&N's limited warranty.
