Looking to Upgrade. Suggestions please?!

[fhsredcats06]

1999 XLT AWD 5.0.

Purchased it about 7 months ago now and to my knowledge the only aftermarket parts on it is a towing package (trailer brake controller, UHAUL towing bar, leveling shocks).

I am currently getting about 13-14 mpg city and 14-15 mpg highway. I would like to upgrade some parts to get these numbers up 2-3 mpg.

My plans:

New Intake (e.g. K&N Cold Air Intake, AEM Cold Air Intake, etc.)
Flowmaster Muffler (No. 524553)

Does anybody have any thoughts/experiences (good or bad) with either of these products? Or perhaps have reccomendations for a different product?

Other thoughts:

I saw a show on TV where they replaced the mechanical radiator fan with an electrical fan in a Dodge Ram and freed up some HP. I was thinking about perhaps doing something similar in my Explorer.

Anybody have experience (good or bad) with this?

Thank you for your input!

Electric fans are always good. The intake i have never found to do much good on its own. Just made my truck sound throatier. This is a great thread for mpg boosting ideas. http://www.explorerforum.com/forums/showthread.php?t=44372&highlight=quest . I thought i read once about disconnecting the driveshafts up front and gaining mpg. Try searching for more info.
