The quickest and most popular way to squeeze every last opportunity for power in your car or truck has to do with air consumption. The air intake system was designed from the factory to provide just enough airflow while reducing engine noise and clutter. Unfortunately, most of these designs are not designed to let the most airflow through to your engine. Think of trying to exercise while taking short small breaths, compared to taking big deep breaths. The difference is pivotal. Let that engine breathe freely with one of our cold air intake kits.

All in a a perfect outcome." —Daniel S from Grand Rapids, MI bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2003 BMW 3-Series.
