K&N High Flow Air Filter.

• Non-Restricting - Dust and dirt will not clog the filter element as quickly as paper or foam because foreign matter remains on the outside of the element.
• Free-Flowing - Even with an outer layer of dust and dirt, there is adequate airflow.
• Replaces stock elements (street legal).
• Million Mile Warranty - You buy it once, clean it and re-oil again and again.
• Unaffected by Moisture - Moisture will not clog the oil saturated element. Even after being completely wet, the filter won't need to be replaced.
• Epoxy coated aluminum screen mesh protects fabric filter media while straightening air flow.
• Accordion fold design provides up to five times the filtering surface of non-pleated filters.
• Oiled premium cotton gauze keeps dirt and debris on the outside of the filter to improve filtering efficiency.
• Sealing bead ensures air tight fit.
• Minimum Service - Cleaning is recommended once a year or when heavy deposits have built up.
