Osprey Hydrophobic Filter Sock – water‑repellent pre‑filter cover for front mount intake systems
Keep your performance car breathing strong in all weathers with the Osprey hydrophobic filter sock. This water‑repellent, dust‑blocking pre‑filter wrap is designed for enthusiasts running a front mount intake, helping to reduce water ingress from rain, road spray and puddles while filtering out dirt and debris. It extends service intervals, protects your air filter, and helps reduce the risk of hydrolock or hydro lock in wet conditions. It even tones down the look of the filter, neatly hiding the purple element if that is not your favourite colour.
Why choose this hydrophobic pre‑filter sock
- Hydrophobic, water‑resistant mesh sheds rain, spray and mist to help prevent water saturation and penetration.
- Acts as a pre‑filter to trap dust, dirt, sand and road debris before they reach the main air filter.
- Helps reduce the risk of hydrolock/hydro lock on road and track in wet weather.
- Extends the life of your cone air filter and maintains intake performance for longer.
- Slim, breathable construction designed not to choke flow on performance intakes.
- Stealth look that mutes the purple filter colour for a cleaner engine bay aesthetic.
- Reusable and easy to clean for long‑term use and lower running costs.
Compatibility and sizing
Made to fit the Osprey 90 mm filter. It may fit other 150 mm filters, but this is not guaranteed.
Ideal use cases
- Front mount intake and front‑mounted cold air intake setups exposed to the elements.
- Daily driven performance cars, track days, road trips and wet‑weather driving.
- Extra protection during heavy rain, winter, or frequent car‑wash use.
Installation and care
- Simply slip the sock over your cone air filter and ensure full coverage of the element.
- Check clearance around bodywork and heat shields after fitment.
- To clean, remove, rinse gently with cool water, allow to air dry fully and refit. Do not oil.
