The very high quality of filtration paper used in Sogefi Filter Division products is specially embossed in order to ensure optimum spacing of the pleats, and maximise the usable surface area.
This ensures the maximum level of dust retention in the filter and air flow to the engine. Sogefi Filter Division products are manufactured in highly controlled conditions, ensuring dimensional stability, a perfect fit into the filter housings, and no by-pass of unfiltered air around the filter.
