This lightweight, breathable wrap acts as the first line of defense against larger debris like leaves, bugs, and heavy dust, keeping it from ever reaching the main filter. By blocking the bigger stuff, the pre-filter helps extend your cleaning intervals and cuts down on maintenance. It also helps protect your filter in rougher environments, whether you’re driving through dry farmland, dusty job sites, or off-road trails. The material is tough but flexible, and best of all, it’s washable and reusable. When it’s dirty, just rinse it off and throw it back on. It installs easily and won’t choke off airflow, so you still get the performance your intake was built to deliver.
