Why not? The additive doesn't clean our intake valves but will clean out the fuel system. It should absorb water/moisture in fuel tank (slightly), clean tank + lines, clean the injectors and pumps. Give it a try, all of my other vehicles are all NA and still yeild great results. Again, because of our DI engines, the difference will not be as "day and night" than some other cars!
