Product description
The Twin Air air filter with bio-oiled coating is a reliable replacement for the Honda CRF 250R/250RX/450R/450RX from the 2025 model year. Designed for off-road riders seeking better filtration and consistent performance, without sacrificing durability.

- Compatibility: Originally designed for the Honda CRF 250R/250RX/450R/450RX (2025 model year).
- Material: Green open-cell foam filter with oil-impregnated coating for excellent seal and airflow.
- Fit: Precision-molded to create a reliable cadet-like seal in the air box, with a sturdy frame-like edge for easy installation.

These compact air filters combine high-quality filtration with effective airflow, allowing the engine to respond faster and maintain power in dusty or dry off-road conditions. The bio oil coating helps trap dirt and maintains a fine filtration layer over longer periods, increasing engine protection without restricting filter airflow. Since the filter is reusable, per-ride maintenance costs are lower, and the engine stays better protected during long trails and races.
