Filter selection was fast and easy as was the ordering and payment process. The filter arrived, well boxed and packed, in less than a week with standard shipping. From unlocking the drivers door on our Genesis 4.6 sedan to shutting the hood was about 2 minutes. The filter was a perfect fit! I have noticed that with my wife driving I'm seeing about a 2 MPG improvement in her in town fuel mileage. (now just about 20) We haven't done an extended highway trip yet but have one planned for late August. Prior to the K&N filter we had manged to milk 28 MPG from the car in steady highway cruise between 65 and 70 MPH. If that creeps up to 30 or higher it will be definitive proof of the efficiency of the new filter.

It is too early to tell as I've only had driven city miles. I plan on taking a 2000 mile trip in May so I will have a better idea on its efficiency and performance.
