My 2004 Expedition loves this intake! ;Feels like I added a brand new engine. It pulls longer, and I can pass other cars easily. When it is in the middle of a power-band I can take it up to about 4.000 RPM as I am accelerating or passing and it is very sporty feeling. I used to drive sports cars and this gives me a little bit of that feeling. Gas mileage has not increased since I am now flooring it all the time. I think when you fist install it you need to drive harder so that the vehicles computers relearn your driving habits for shift points,etc. I have had it 2 weeks now and I plan on driving it easy now to see if the gas mileage has increased. I have to remind you, if you get this do what I did and get a brake check. I had ceramic pads and new rotors installed on schedule, and I timed it as such. You will drive faster with the intake so keep that in mind. I also run [brand] oil, [brand]plugs, and low resistance tires. I normally avg 15.2 city, lots of red lights.

Great product. Easy to install. The instructions were clear and concise. It only took 60 minutes. Performance seems to be as specified. I really like the sound it makes during acceleration. I would definitely recommend this product. Thanks K&N
