Ramair Performance Pleated Replacement Air Filter for BMW 1.5 B38, B37 & N13

Upgrade your BMW’s airflow with the Ramair Performance Pleated Replacement Air Filter (PPF-2008). Designed to fit directly into the OEM airbox, this filter replaces the restrictive paper element with a high-flow nanofibre filtration media that maximises airflow while maintaining excellent engine protection. The pleated design provides a larger surface area for smoother intake flow, improving throttle response and efficiency. Built with precision injection-moulded construction, stainless steel reinforcement, and reusable media, it’s a long-lasting upgrade that blends performance, reliability, and ease of maintenance.
