    The coupling hose for the throttle body (08698) and the coupling hose for the filter adapter (08699) were incorrect. 08698 should go on the filter adaptor and the 08699 should go on the throttle body. Otherwise looks great and sounds even better.

    It was very frustrating to install until I was told that I had the wrong gaskets for the ends of the tube. K&N shipped the right gaskets to me by UPS next day air and I was driving before noon the next day. If anything happens like that again, I will ask them to ship it " next day air with early AM delivery" (on their dime). I like the sound of the hi flow air intake, seams to have more nut, but I don't see any change in fuel economy on my Ford F 150 with a 5.0 V8 engine

    Always buy K&N cold air intakes
