Air filter Poliair for Yamaha YZ 250 97-25

POLIAIR air filters are THE ONLY built with THREE LAYERS OF SPONGE having three different porosities to retain all types of impurities.

Are made in Holland where, due to the particularity of the sandy soils, the most significant experiences in the sector have been gained.

As is known, 4-stroke engines can have a backfire from the intake that could reach the air filter and set it on fire. To remedy this problem, the manufacturers install a flame-extinguishing screen before the filter, but this causes a decline in performance!

For this reason, POLIAIR filters are built with a special self-extinguishing material to allow the elimination of the flame-extinguishing screen, increasing engine performance!

Don't use gasoline for clean the air filter, but look on our shop for specific products: CLICK HERE.
