To achieve optimum performance, combustion engines require clean intake air. Here is another hallmark of OKYIA air filters: the high dust holding capacity ensures it is the end of the road for all dirt particles. No matter whether it's dust, pollen, sand, soot or even water droplets - thanks to the highest degree of dirt separation and high mechanical stability, OKYIA filter air filters even the smallest particles out of the intake air. This enables an optimum composition of the fuel-air ratio and ensures that the engine performance is consistent.
