Air filter for car 1, high filtration precision: All the larger particles by filtration> 1- 2 um to maximize the reduction of air into the fuel chamber of the impurities. 2, high filtration efficiency: reducing the number of particles through the filter. 3, to prevent engine wear occurs earlier. Prevent air flow meter damage. 4, the pressure is low, ensure that the engine has the best air-fuel ratio. Reduce filtration loss. 5, filtration area, high dust capacity, long service life. Reduce operating expenses. 6, small installation space, compact effectively prevent impurities from the bypass fleeing engines. 7, to prevent the emergence of suction filter deflated phenomenon, resulting filter breakdown.
