The best air filter for the Honda CRF 250R is the one that offers the best filtration, extends maintenance intervals, and ensures clean engine breathing.

Highlights of the FunnelWeb ProLine filter:

Like all FunnelWeb filters, the ProLine filter features a single-layer foam with a cut profile, of unique density, which doubles its external surface without increasing its size. The ProLine filter captures dirt, dust, sand, and mud over a larger surface area, ensuring optimal airflow for maximum engine performance and reliability.

The single-layer polyurethane foam of unique density has the advantage of being easy to clean and retaining its original shape even after numerous washes. Overall, compared to traditional foam filters, the FunnelWeb filter offers better protection against dust ingestion, longer maintenance intervals, and high airflow even when dirty.
