Don't let a flimsy paper filter get between you and true performance. The PERRIN High Flow Panel Filter is a direct drop-in replacement for the stock air box on the 2008-2021 WRX/STI, 2005-2009 Legacy GT, 2013-2017 Crosstrek and 2014-2015 Forester XT. The dual-stage open-cell foam element, sprayed with a special oil coating, captures dirt and particles while allowing increased airflow for improved throttle response and horsepower. Washable and reusable - clean and re-oil with the PERRIN cleaning kit (sold separately) and never buy a disposable filter again.
