Ramair Performance Foam Induction Kit for BMW E30 316i & 318i

The Ramair Performance Foam Induction Kit for BMW E30 316i & 318i replaces the restrictive factory airbox with a high-flow twin-layer foam system to unlock smoother airflow, crisper throttle response and a richer induction note. Built around a rigid T304 stainless support cage and hand-assembled in the UK, the filter delivers near-unrestricted flow while maintaining the filtration levels essential for long engine life. Supplied with cold-air feed ducting and a full fitting pack, it installs cleanly and is easy to service with the CK-003 cleaning kit.
