Product Details
The K&N 57S-2003 performance airbox is built with an injection-molded housing that connects directly to your factory intake hose, replacing the restrictive stock air filter and housing. This design smooths and straightens airflow, allowing your N54 engine to breathe more freely. More air means you'll notice improved power and acceleration across the entire RPM range.
Installation is straightforward, using the existing space of your factory air box and requiring commonly available tools. The removable lid makes it easy to access the filter for cleaning when needed. This air intake system is constructed to last for the life of your vehicle and is backed by K&N's No-Hassle Lifetime Limited Warranty.
