Perrin Replacement Foam Filter (3.125" Inlet) - Subaru WRX / STI 02-07

Description

This is a direct replacement for PERRIN WRX & STI Cold Air Intake Systems.

Two-Piece Design
PERRIN Filters feature a unique two-piece design allowing the user to remove the foam filter element for easy cleaning. Please check the Inlet Inside Diameter (I.D.) of the filter you are replacing as there are variations in intake design.

Open Cell Foam Element
PERRIN foam filters are made of reticulated polyurethane foam which offers a 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.

Clean and Protect
Keeping your air filter clean is essential for optimal performance and longevity of your vehicle's engine. By following these steps, you'll ensure that your PERRIN Air Filter continues to deliver peak efficiency.

Filter Tech
PERRIN Intake filter elements use open-cell foam to capture dust and dirt. Washable and reusable, PERRIN foam filter elements can last the life of your vehicle. Foam filter elements offer superior performance with minimal airflow restriction and amazing dust-holding capacity.
