An integrated filter lid has a filter surrounded by an outer frame. The outer frame is adapted to seal around an inlet opening of an air box which has a primary filter for filtering air prior to being provided to an engine. The integrated filter lid covers the inlet opening of the air box and filters the air before the air enters the air box. With integrated filter, outside air is filtered at least twice before being provided to an engine, the first time by the filter in the integrated filter, and the second time by the primary filter in the air box. The integrated filter also increases the flow of air into the air box, thereby enhancing performance of the engine.
