My husband installed this in my 2009 Scion xD automatic in less than an hour. Acceleration has improved, seems to have a bit more oomph in 2nd gear. I haven't run a full tank of gas thru the car since the install, so I can't say yet about gas mileage improvement, but it seems to be taking longer than usual to run thru a tank of gas, so my guess is there will be some improvement there as well. We use K & N products in our vehicles, and will continue to do so as long as we're driving.
