It’s been two weeks since I did this mod and here is my opinion, I have better acceleration and better gas mileage. One thing of note I just went over 32k miles and I think that filter was wearing out. Last year I was getting from 29.2 to 30.7 mpg at 75 Mph and right before I cut the filter out I was down to 27.2 to 27.8 at 75 Mph and the car was starting to feel sluggish. Now all my power is back and maybe a little more and my gas mileage is 29.7 to 31.2 at 75 Mph.
These tests were done with the cruse control on 75 for most of the trip and during my 72-mile trip to work almost all freeway 1/2 hills and the other half is flat ground.
