The service honestly was great, not only was the filter on sale when I purchased it but shipping was included and it got to my house in Canada in 2 days. My fuel ecocnomy has definitely gotten a bit better.

Not sure, but I think I feel a HP boost when accelerating. I havent really noticed better gas mileage.
