This is a straight replacement for the 2002-2007 WRX & STI intake systems made by PERRIN Performance. Any intake system that accepts a 3.125" filter can use it as well. PERRIN Filter features a unique two-piece design allowing the user to remove the foam filter element for easy cleaning. This filter has a 3.125" I.D. Inlet. PERRIN foam filters are made of reticulated polyurethane foam which offers minimal air restriction. The filter element is sprayed with a special oil that adheres to the foam making the poly matrix sticky to retain dirt. Foam filters do not block dirt, they grab it, suffering only minimal drops in air flow as they filter dirt, maintaining air flow levels when other filters would clog. Remove months of oil and grime by simply spraying on this easy-to-use cleaner. Just let it sit on the filter element for a few moments and simply rise in the sink. Once your filter is dry, just spray on a fresh coat of oil and you are ready to go. PERRIN Intake filter elements use open cell foam to capture dust and dirt. Washable and reusable. PERRIN foam filter elements offer superior performance with minimal airflow restriction and amazing dust holding capacity.
