UNI AIR FILTER KTM DIRTBIKE NU-1415ST

MFG Part Number: NU-1415ST

• The principal 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 the dirt to pass through 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 surface life of the air filter element
• When the filter is sufficiently dirty it can be easily washed, re-oiled and re-used
