Twin Air Standard Air Filter - Honda CRF250R 2004-2009

While designed for the Honda CRF250R 2004-2009, it is slightly smaller than the stock filter to improve airbox circulation. It provides a secure fit when installed correctly.

The dual-bonded foam construction offers superior filtration by trapping both large debris and fine particles, while also allowing for increased airflow compared to single-layer filters.

For optimal performance and filtration, especially in dusty conditions, it is recommended to lightly oil the filter. Use a filter oil specifically designed for foam air filters.

Cleaning frequency depends on riding conditions. In dusty or wet environments, inspect and clean after each ride. In cleaner conditions, cleaning every few rides may suffice.

While the adhesive is durable, it is best to use a dedicated foam air filter cleaner. If using gasoline, do so sparingly and rinse thoroughly. Prolonged or repeated exposure can degrade the foam and adhesive.

The Manufacturer Part Number (MPN) for this Twin Air Standard Air Filter is 150209.

Ensure the airbox is clean and free of obstructions. Verify that you are using the correct filter for your specific Honda CRF250R model year. The filter is designed to be slightly smaller; ensure it's properly aligned and gently pressed into place.

Check for proper filter installation to ensure no air leaks. Verify the filter is adequately oiled (if applicable) and not clogged. Re-inspect the airbox for any blockages.

Use only recommended cleaning solutions and solvents specifically designed for foam air filters. Avoid prolonged exposure to gasoline or overly harsh chemicals, as this can break down the adhesive and foam integrity.
