Ramair Performance Foam Induction Kit for BMW E39 5 Series

Description

The Ramair Performance Foam Induction Kit for BMW E39 5 Series (520i & 523i) replaces the restrictive OEM airbox with a free-flowing foam intake to unlock smoother airflow, sharper throttle response and a richer induction note. Using Ramair’s dual-layer foam and a rigid T304 stainless support cage, the system delivers near-unrestricted flow while maintaining the filtration levels essential for long engine life.
