Product Description

The aFe 10-10408RM is a Magnum FLOW Pro 5R oval air filter engineered as a direct OE replacement for the 2008-2015 Audi R8's factory airbox. It uses five layers of pre-oiled cotton gauze media with progressive layering, so airflow stays strong even as the filter accumulates dirt over its service life - a meaningful advantage over a disposable paper filter that restricts more as it loads up.

The filter's full 360-degree polyurethane frame is designed to conform tightly to the factory housing, creating a reliable seal without gaskets or sealants while remaining durable through repeated heat cycles in the engine bay - a common weak point for lower-grade filter materials. Combined with the rounded, deep-pleat design, this maximizes usable filter surface area for both flow and dust capacity.

Because it's washable and reusable rather than disposable, this filter is meant to be cleaned and re-oiled periodically using aFe's Power Cleaner and filter oil rather than replaced at each service interval, making it a straightforward long-term upgrade for R8 owners looking for a factory-fit performance filter.
