Like all FunnelWeb filters, the ProLine Filter features profile cut, single layer, single density foam that doubles the external surface area of the filter without increasing the original filter size. The ProLine Filter traps dirt, dust, sand and mud over a larger area on its outer surface, ensuring optimal air flow is maintained for maximized engine performance and reliability.

The single layer, single density polyurethane foam has the added advantage of being easy to clean and the ability to maintain its original shape after numerous washes. Overall, compared with conventional foam filters, FunnelWeb offers more protection from dirt ingestion, has longer service intervals and maintains high airflow rates when dirty.

Superior Filtration:

This should be the last oil filter you will ever buy. Made from laser cut, medical grade, 304 stainless steel micronic filter cloth, this filter provides 200% more filter area in many cases. Most good paper filters will pass particles in the 90 to 95 micron range, and some tested, as much as 300 microns. Sand is about 125 microns and a white blood cell approximately 25 microns. Flo's stainless filter catches items down to 35 microns "absolute", which is about 3 times better than most good paper or brass filters. The pleat seam is welded, able to withstand up to 600 degrees in our filter, not glued, like paper filters.
