Osprey 90mm Cone Air Filter Pre-Filter Sock - Hydrophobic, Washable, UK Stocked

For owners running an Osprey 90mm cone air filter - no more, no less - this hydrophobic pre-filter sock adds real-world weather resilience. It sheds rain, mist and road spray to lower hydrolock risk on track days or wet A-road commutes.

• Exact fit: designed solely for Osprey 90mm cone filters - not universal, not stretchy, not guesswork
• No oiling, no replacement: rinse with cool water, air dry, refit. Reusable for years
• Stealthy & functional: slim profile avoids airflow restriction while toning down bright filter colours
• UK stocked: ships same day, no import fees or delays

Not a fix for intake faults. Not a substitute for proper filter maintenance. Just smart, simple protection where it matters most.
