UNI Foam Air Filter for BMW Motorcycles
Foam air filters offer a new and more effective filtration system for your BMW motorcycle. Each polyurethane foam filter should first be wetted with our specialty oil, collecting incoming dirt and debris to keep it out of your engine. The oil allows every inch of foam to collect dirt. Its durable material can be washed, re-oiled and reused time and time again to maximize convenience and affordability.
WHY FOAM IS A BETTER AIR FILTRATION MEDIUM THAN PAPER OR GAUZE?
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 on the strands of the web-like cell structure of the foam. This makes it 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 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.
