Uni Filter Inc. has been manufacturing foam air filters since 1971.  They feature seamless polyurethane foam as the filtration media.  They have high air flow and superior filtration abilities, making them the choice for many motorcycle, dirt bike and ATV riders.

Uni Air Filters are the only air filters that are two air filters in one.  This unique design produces improved air flow, better dirt stopping ability, and easier and more thorough cleaning.  Both layers of the filter should be oiled using only UNI filter oil.
