MXA PRODUCT SPOTLIGHT: UNI TWO-STAGE FOAM AIR FILTER
“For over 50 years, Uni Filters have been unsurpassed in engine protection and performance. The unique, two-stage filter design allows your engine to produce more horsepower and torque than any other air filter. Uni Filter is the choice of the greatest off-road racers of all time because of the Uni Filter’s ability to hold large amounts of dirt and still provide excellent air flow.” —Uni Filter’s Tom Gross.
How a Uni Foam Air Filter works: The air filter is manufactured with “Open Cell” Polyurethane Foam which is wetted with a specially developed foam filter oil. The “sticky” filter oil is suspended in the path of the dirty air on the strands of the web-like cell structure of the foam. This makes it virtually impossible for dirt to pass through the depth of the filter without sticking to the strands.
As the outer strands become loaded with dirt particles, the wetted strands down stream start trapping dirt, allowing the entire thickness of the air filter to be utilized. This prevents surface loading or air restriction for 80% of the service life of the air filter element. When the filter is sufficiently dirty, it can be easily washed, re-oiled and re-used.
