Just like our air filters, this 1/2” open-cell polyurethane foam pre-filter is washable and reusable. Simply tap it to remove excess debris between your regular cleanings, and wash it with aFe POWER Cleaner when you service your air filter. Pre-filters provide added peace of mind for those who operate their vehicle in dirty environments. This foam component captures large particles before they reach the air filter, increasing efficiency and dust-holding capacity without negatively affecting airflow. For even further protection, it can be treated with aFe’s air filter oil.
