Your car maintains a high MPG with the K&N filter? My MPG dropped enormously while I had the K&N installed, which is why it's now lying on my toolbox in the garage. What did you do differently? Is it the cone filter or a drop in filter? How weird... Did you reset your battery after installing it?Albert said:Hey all, just wondeeriung what kind of mileage you're all getting. I took a trip to Chicago (from Detroit) and managed to get 30.7 MPG running pretty much at a constant 75-80 MPH. I was impressed. Car is stock aside from a K&N filter.
