Open Cell Foam Element - PERRIN foam filters are made of reticulated polyurethane foam which offers a minimal amount of air. The filter element is sprayed with a special oil that adheres to the foam making the poly matrix sticky and retain dirt. Foam filters do not block dirt, they grab it! All while making minimal drops in air flow as they grab dirt! What does this mean to you? More dirt collected, more air flow and no clogs!
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 rinse away the cleaner and dirt. Once your filter is dry, just spray on a fresh coat of oil and you are ready to go.
Jeff Perrin: The Rumor Buster - Don't be fooled by K&N or Dry filter hype that they filter better and make more Horsepower or flow more air. Its the small details they are not telling you about that might steer you away from the filters.
