Uni Foam Air Filters use polyurethane foam as the filtration media because of it's superior dirt capturing abilities. The principle of how foam air filters work is simple: 'Open Cell' Polyurethane Foam is wetted with specially developed filter oil. The 'sticky' filter oil is suspended in the path of the dirty air making it impossible for dirt to pass through the depth of the filter.
Delayed Shipment Notice
Several UNI Filters are on backorder, with some expected to ship by mid-to-late December. Exhaust orders may receive their exhaust system without the UNI filter.
