The air filter is the most important element in preventing engine wear.
For this reason, POLIAIR filters are (the only ones) built with three layers of foam with three different porosities to trap every type of impurity.
Made in the Netherlands, where, due to the particular sandy terrain, the most significant experience in the field has been gained.
As is well known, 4-stroke engines can backfire through the intake, and the flame could reach the air filter and set it on fire. To avoid this problem, manufacturers install a spark arrestor screen before the filter, but this reduces performance!
POLIAIR filters are made of a special self-extinguishing material that allows the spark arrestor screen to be removed, increasing engine performance!
