Air Filter
I've got 1100 miles on my new 2003 F-150 Supercrew, 4.6L, and it seems pretty anemic.
I've been considering putting in the K&N filter, but should I just replace the existing filter with a drop-in, or replace the whole thing.
I live in Tucson, it's over 100F already and climbing. Lot's of dust in the air as well.
Thanks,
Walker

I just did the K&N thing. You may get a little more if you get the kit that actually takes in air from the fenderwell and not the underhood area. The hot air under the hood is not good for making more power.

Like lxman1 said you dont want to draw air from under the hood.
If you get a K&N be prepared to clean your MAF sensor a little more often than normal. The oil from the filter seems to foul up the MAF quite easily.

I beg to differ on the idea that air from under the hood is bad. Instead of buying K&N's setup I simply seperated my OEM air filter housing,unsnapped the half closest to the firewall,tossed out the connecting piece to the firewall,cut off excess of housing behind the plastic tabs that secure it to the fenderwell then reinstalled. I seem to get plenty of fresh air from around radiator etc. and most definitly gained some in the low end torque and horsepower areas.By the way I live in Louisiana where we know all about the heat and humidity.

Does'nt appear to be a problem. Although I am going to install an after-market hood scoop with custom,handmade (by me) ducting that will effectively funnel air directly into OEM filter housing there-by (hopefully) creating a ram-air system.

Be very careful what you are trying to do. The dynamics of airflow
in the intake system are complicated. Anything you do to cause
turbulence, or uneven airflow across the MAF sensor element
will cause a "lean" condition, resulting in pinging, poor performance, etc..
