UNI’s first foam air filters were made in 1971. Polyurethane foam had been used as an air filtration media for many years, but not until Uni Filter introduced the patented Sock” Filter for motorcycles and small engines in 1973 did it receive mass acceptance. This dependable High Air Flow Filter launched a product line that covers virtually all popular Dirt Bikes, Street Bikes & ATVs.
