An air filter assembly module, belonging to the field of auto parts, and that was developed to improve air supply to internal combustion engines and their performance, includes: a dirty air admission inlet; a chamber, in which the inlet opens; an air filtering element housed in the chamber; a clean air outlet, derived from the chamber and positioned downstream the filtering element; means of noise reduction; an apparatus for recirculation of oil vapors from the oil sump to the combustion chamber; an airflow converger located at the outlet of the module having selected geometry in order for the airflow, subject to constant or variable flow conditions, to be converted from turbulent flow with high recirculation rate to laminar flow with minimized or annulled recirculation rate and turbulence intensity, all incorporated and assembled in a housing assembly located at the top of the engine compartment.
