As compared with the regular air filter I haven't noticed any improvement in gas mileage or acceleration. I do appreciate that it will keep many paper filters out of the landfill. Maybe over time I will see a difference, but my MDX "man van" still gets the same mileage and appears to have the same acceleration as before. If for no other reason--buy the filter to reduce waste.
