2004 Expedition 4.6L Cold Air Intake

[JohnnyP1975]

Hello, new to the forum. I got a '04 expy 4.6L with 22Kmiles on the odo, and i am looking into cold air intakes with best horsepower gain.

If you want looks, i.e. a chrome tube, then get K&N.
If you looking for the best bang for the buck.. Gott's mod.
Strictly for HP.. I think they are all the same..
Just my 2cents

My rear wheel hp more than doubled after I installed my K&N.

Did do a few other mods at the same time though so it may not be all due to the filter.

I would like to get horsepower like the 5.4L engine, and at the same time save gas.

Well you pretty much do have the HP of the 5.4L as they aren't too far apart. Its the torque that the 4.6L is down on.

All intakes offer almost similar functionality and don't expect too much improvement. Maybe adding a free flowing exhaust can help along with CAI.
