Product Details
Description
The OEM airbox in the BMW E9X 335i/335is N54 just does not cut it. Extend the life of a filter, improve airflow and pickup HP with the K&N 57i Series Air Intake System 57S-2003.
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.
