Had a K&N FIPK II on my F-150 (5.4L). I thought it made a difference and I only had to buy 1 filter (the K&N in the kit) during the 7 years I owned it. I think it made an improvement in power, plus you could hear the truck breathing under the hood too.

Please tell us what drives your "I hate it" immediate and only response. Did it taste bad or what. I always wonder what drives immediate bad responses and usually it is something that the dealer or order department did and not the product. My guess is that you really don't know enough about them to like or dislike them, just someone ticked you off.......correct?
I'm always looking for a little performance "edge" with everyone of my vehicles, from the 73 Jensen Healey to the 05 F150 (which I just bought). I've put K&Ns in 2 Rangers, 2 Sport Traks (for friends), 1 E150, 1 E250, a Chrysler Sebring convertible, 2 PT Cruisers, and a Fiat Spider. Now, the "edge" in some if these vehicles is that I never have to buy another filter, on others, I feel I've gotten a little more "umph" out of them with the K&N. Now it's time to put one on the F150. I've never dealt with a cone in a can before, but it appears to be sucking cool air in from under the fender well. Is a conical K&N my best (and most economical) bet here? I kind of like the howling moan of a V8 sucking up non-renewal resources, but can live without it if I have to.....
i put a series 63 intake on my 07 expedition. It seems to have given it slightly better throttle repsponse and slightly better gas mileage as long as I take it easy. These are the good parts.
now the bad is that it created a very loud hum / droan from 2500 rpms upward. I even purchased some noise reduction material and wrapped the intake pipe and intake shield with it and it still is wayyyy too loud. I dont know what else to do. I am pulling a trailer tomorrow and will see how it sounds under a heavier load, I may end up pulling it and going back to the stock intake with a drop in K& N filter.
I have the complete K&N intake system on my PSD anf love it-Better and quicker throttle response, Turbo spools up quicker, and mileage is up about 2 MPG! Go for it!
I wont be wronged, I wont be insulted, and I wont be laid a hand on-I dont do these things to other people and I require the same from them! jw

I've got a 2001 F-250 SuperDuty V-10, pulling a 11,000 lbs fifth wheel, love the K&N cold air injector (easy to intstall) I' get 16 mpg empty and 9 loaded, also installed a Banks headers system, had our mechaNIC TELL ME THAST IT IS tweaked TO THE MAX. I would strongly suggest adding a Trans temp gauge and Vaccum Gauge too, auot meter or glow shift if you want some thing different.
When I first installed the stock replacement K&M i noticed a .5 mpg increase and greater acceleration.
I'm getting ready to install the same 63 series K&N intake/filter kit; also have B-quiet Ultimate to wrap everything up with. But after reading about your experiences with noise am a little concerned about your comment on taking it out. I am putting this on primarily for highway mileage improvement so I may be on the low end of the RPM range you start to hear the noise at. Also, I don't do any towing.
Are you still considering taking it out, especially in the new $4/gal era?
Also, I thought I saw some very good pictures and comments on the K&N installation? Was that from you? (I can't find it here now...)
