I could tell a difference after 5000 miles in my engine. More power and mpg. But then again maybe I had gotten past trying it out everytime I took off . The automatic has a more restricted exhaust also. My worse has been 17.5 and that was when it was new and I had pedal to the metal often. Now I just enjoy the ride. My wife's Chrysler 300C get's a average of 18 mpg. And a best of 24 on the road most of the time. I have a drop in K&N filter in both.
