Ramair Performance Foam Induction Kit for BMW E81/E88 116d & 118d

The Ramair Performance Foam Induction Kit for BMW E81/E88 116d & 118d replaces the restrictive OEM airbox with a high-flow, twin-layer foam intake to unlock smoother airflow, crisper throttle response and a more engaging induction note. Handmade in the UK and engineered around a rigid T304 stainless support cage, the filter delivers near-unrestricted flow while maintaining the filtration levels your N-series diesel needs for long-term reliability. The kit includes cold-air feed ducting and a complete fitting pack for an OEM-like install and easy serviceability with the Ramair CK-003 cleaning kit.
