I recently installed a K&N FIPK on my 2002 F-150 4x4 4.6L. And was very impressed with the results. Increased throttle response and horse power. In town not so much, but driving in the mountains where I live, it made a big difference. And if you like the sound of a V-8, you will like this. The sound under the hood changed dramatically. The more you put your foot into it the more you hear it. Very easy to install.

 

Most people don't see any performance and/or MPG improvement at all. Remember, louder does not equate to more power......

 

Plus, you might even learn how to clean the MAF sensor.

 

you are correct louder does not mean more power but the fact still remains
I noticed a significant improvment in throttle response and horsepower
Maybe the reason I see an improvment that others may not is because I live at 8400 ft above sea level?

 

I'm also getting 2 mpg more I didn't think that would change but it has

 

maybe I can learn how to clean this? Please explain. Thanks

 

The oiled air filter can/will get oil on the MAF and prevent it from "sensing" properly.

Super easy to clean however. Takes all of about 90 seconds. With most of the time spent lining up the latch on the stock air box with the drop in filter or loosening the clamp and sliding the filter off on the FIPK.

I clean the MAF pretty much every oil change - whether it needs it or not. Most likely the only time you'll NEED to do this is after you've cleaned and re-oiled it and you put too much oil on the filter.

To clean it I simply pull the airbox apart and seriously hose the little filament with an electronic parts cleaner that leaves no residue. I would not try to clean it by physically touching it with anything. A broken MAF can be expensive to replace. I've done this 25-30 times on my F150 and about 15 times on my old Mazda/Ranger.

I had not thought of that. Great advise. Thank you so much for the info.

 

I have a drop in K&N in my truck, and cleaned and oiled it 4000 miles ago and have had no problems with the MAF so far. I did notice with a clean filter my truck is getting better milage.

 

Just a follow-up on what pilot10 said, it wouldn't hurt to disconnect the neg battery terminal after a maf clean so the PCM can re-learn the new readings it will recieve with a nicely cleaned maf. Just make sure to leave it disconnected for about 1/2 hour or so for best results.

 

If you short the negative battery cable (once it's off the battery) to the positive cable, this will discharge the capacitors in the PCM, resetting it
immediately, eliminating the need for a long wait.

 

wow I'm really going to school here thank you all for the positive feed back

 

I was always told to just turn on the headlights and flip on the high-beams to discharge the caps...never heard of the way you do it but it sounds alot quicker.

 

The headlights will work too, anything to provide a current path to discharge the caps.
