Upgrade your BMW's engine with the K&N Engineering Performance Airbox designed specifically for 2013-2016 BMW 2, 3, and 4 Series equipped with N20 engines. This high-performance air intake system replaces the factory air filter and housing, significantly reducing airflow restrictions and smoothing incoming air flow. The result is increased airflow into the engine, leading to improved horsepower, torque, and acceleration across the entire RPM range. Its fully enclosed, injection-molded design connects seamlessly to the factory intake hose, ensuring a secure fit and reliable operation. The removable lid allows quick and easy access for filter cleaning and maintenance, making it a practical upgrade for daily drivers and performance enthusiasts alike.
