The development of this special foam represented a major advancement in air filtration technology. Foam air filters now combine great airflow capability, huge dust holding capacity, and very high filtration efficiency for extremely small particles.

Fully reticulated (open pore) foam is a honeycomb of tiny, interlocking cells of uniform size, which create an impossible journey for dirt particles since there are no straight-through passageways. Each passageway (16 to 25 mm long) is like hundreds of very small centrifugal/oil bath filters connected one to another. In this way, foam traps and holds the particles throughout the entire volume of foam. This is why they are referred to as "full depth" filters in contrast to the paper or gauze elements, which are screens, or "surface type" filters. The cell strands stop the dirt, while the oil film holds the dirt like fly paper until removed for cleaning.

FOAM FILTER OIL IS NECESSARY
FOR PROPER FILTRATION!

Your air filter is the lifeline to your engine......

          Improper maintenance can result in engine failure.......

Please read the following instructions carefully to achieve maximum engine protection and performance.

Uni Filter Oiling Instructions
Remove the filter frame (if applicable) and saturate the foam element with Uni Foam Filter Oil.

UFF-16 Uni Liquid Oil: Pour into pan or tub, and dip the filter until there is complete coverage with oil. Next squeeze out all you can...(do not wring out) then dab filter with paper towels to remove excess oil. If your filter has a rubber flange, be sure to clean mounting surface free of oil.

UFF-100/104 Aerosol Filter Oil: Spray the filter inside and out until the filter has complete coverage with oil. Next work the oil into the foam using your hands. Repeat this step once more, and then dab filter with paper towels to remove excess oil. If your filter has a rubber mount flange, be sure to clean the mounting surface free of oil.

Clean filter frame, clean filter mounting surface and air box. Check air boot and mount to carburetor. Next reinstall filter frame (if applicable) back into the filter element. We recommend using sealing grease in our exclusive "Ultra Seal" grease groove.

Now you're ready to install the best air filter on earth!

Uni Filter Cleaning Instructions

GREASE CUTTING CLEANER IS NECESSARY FOR PROPER CLEANING!

Remove the filter frame (if applicable). Next saturate the foam element with cleaner.

UFC-300 Uni Foam Filter Cleaner: Spray generous amounts of Uni Cleaner on the inside & outside of the filter. Let it soak approximately 3-4 minutes. Rinse out the filter element in warm water until clean. A second application may be necessary for heavily soiled elements. Next you must let the filter dry completely. Very important! Re-oil per instructions, and you are ready to go.

Grease cutting cleaner: Products like Simple Green, dish soap, or mild solvents can be used if Uni Cleaner is not available at the time of cleaning. Pour cleaning solution into a bucket; dunk the filter in multiple times until clean. Rinse with warm water. Next you must let the filter dry completely. Very important! Re-oil per instructions, and you're ready to go.

Clean filter frame, clean filter mounting surface and air box.

Now you're ready to oil, and install the best air filter on earth!
