Polyurethane foam had been used as an air filtration media for many years, but it received mass acceptance when Uni Filter introduced the patented Sock” Filter for motorcycles and small engines in 1973. This dependable High Air Flow Filter launched a product line that covers virtually all popular Dirt Bikes, Street Bikes & ATVs.
