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

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.

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.
