If your car is used on the street then yes, use a filter. If you're racing it and you're getting maybe 300± miles per engine rebuild, then no, a paper/fiber filter is typically too restrictive (assuming your engine is built with extremely high tolerances) to have any benefit. Use a steel mesh filter on the inlet housing to prevent animal babies from entering there and coming out as dead animal babies, ha ha ha.
