K&N Engineering Part 57S-2001 Performance Airbox for BMW 2, 3, and 4 Series N20 Engines

The K&N Performance Airbox is designed to dramatically reduce air flow restriction as well as smooth and straighten air flow. Replacing the restrictive factory air filter and air box allows your engine to inhale more air than with the factory air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. A fully enclosed injection molded air box connects to the factory air intake hose. The removable lid provides easy access to the filter when cleaning is required. This performance air box is relatively easy to install. The required tools are commonly available and it uses the previous air box space. These air box systems are built to last for the life of your vehicle and they're backed by K&N's No-Hassle Lifetime Limited Warranty. Some K&N 57S Series Performance Airboxes are compliant with the latest TUV emissions and sound regulations. Check the K&N catalog or website for vehicle applications and specific TUV status for each vehicle and air intake. K&N's easy-to-install performance air box replaces the restrictive factory air filter and air intake housing delivering a power gain. This power boosting air intake comes with K&N's No-Hassle Lifetime Limited Warranty.
