      i needed more horse power for hauling a camper and after checking that my throttle opened fully, I could see it needed more air intake. I modified air box and added new filter, seems to work ok.

      Noticable difference as soon as I put the filter in. Works great, direct fit. My 2000 Expedition idels much better, accelerates easier and I've even noticed about a 10% gas millage increase. Highly recommended for all cars.

        Comments about K&N Replacement Air Filter:

        I had read about K&N and their claim of increased performance and fuel mileage. Since I had a coupon I decided to give it a try. I love it. My V8 F150 has better pickup speed, smoother cruising, more power and better fuel mileage. I have picked up 3.2 mpg highway and 2.1 mpg city. I plan to replace my Lincoln air filter as well.

          I've used K&N filters in cars, trucks, & motorcycles. There may be some fuel efficiency, but that's not why I put them in. There is a noticeable improvement in performance, and the filters are reusable. They pay for themselves.

            Typical K&N quality product. I bought this filter for my Ford F-150 XLT 5.4 L after having good results with K&N filters on my Harleys. Having a reusable performance filter is great, plus it uses the same cleaning kit as the filters on my bikes. Overall, i would recommend purchasing and using a K&N filter for anyone wanting a quality filter at a good price. I'm not sure if the truck is getting better gas mileage because I just put it on, but it did help on my bikes and the truck seems to idle smoother and run better.

                These filter are awesome. Cost 3x as much as a factory filter but is reusable and will pay you back if you keep the car / truck a few years.

                  Comments about K&N Replacement Air Filter:

                  I use K/N filters in all of my vehicles. This addition to the F150 is recent but I am sure it will perform like all the others. No more going to the store for another paper filter. After 2 paper filters, you are paying more for an inferior quality product and you continue to pay if you replace your air filter every 15k. Maintenance on these things is a breeze. You just take the filter out, spray it with some Purple Power or other cleaner, hose it down with some water and if you have a compressor- hit it with some air and it is like new.
