An air filter assembly for use with an internal combustion engine is provided. The air filter assembly includes a casing having an inlet configured to receive air from the environment, the casing having a passage, and an outlet disposed downstream the passage. A collection chamber collects particles from the drawn air. The collection chamber is disposed downstream from the inlet and upstream from the outlet. A partition is disposed between passage and the collection chamber. The partition has openings configured to allow particles to pass through. A side port is downstream the partition and in fluid communication with the passage. An internal combustion engine utilizing the air filter assembly is also provided. The internal combustion engine includes an air manifold, a combustion chamber and a filter. The air filter assembly is disposed upstream the filter.
