Brand New Expy Owner

[grantpa]

Hi just want to say hello to you all. Just picked up an '00 Eddie Bauer Expedition with 4.6L Triton, etc. with 170K miles but in excellent condition-inside and out.
I'm coming from a '93 Jeep Grand Cherokee so the size difference is noticeable.
What modifications do you recommend for a little more power and mpg's?
I guess I'm asking what mods does the 4.6 respond to? Not looking to sink a ton of $$$ into it but as a life-long tinkerer and shade-tree mechanic-I just can't leave well enough alone.
I'm thinking High-Flow Dry air filter replacement, cat-back 3" exhaust with a Flowmaster Super 50 for starters. I've seen on vids that Motorcraft plugs are best and not to waste money on Platinum, Iridium, etc. What say you? Is there any merit in upgrading the ignition system, i.e., MSD, Accel, etc. box?
What about trans upgrades-coolers, shift kits, etc.? No, I do not plan on towing much if at all. my intended purpose for this car is long distance highway trips (approx 1600 miles RT) in comfort about twice a month. Suggestions? Thanks in advance.

Welcome! I'm new to this site myself.
I'd start with the basics...

-High flow air filter (keep the stock box)

-Gotts mod for your intake where it meets the fender (replaces the tapered snorkel with 3" PVC)

-Flowmaster cat back (I prefer single out)

-Edge programmer

This will wake her up a bit for less than $1K

Have fun!

Thanks Mike! Already installed an Upgr8 High Flow replacement air filter today and have a Flowmaster 50-Series Delta Flow Stainless Steel muffler-3" In/Out that I'll be mounting with 3" pipe from the cats-to-the-tail. I searched gotts and came up with no how to's, just references. Maybe I'm not searching correctly? What exactly is this mod and where can I find 4.6L, Expo-specific how-to vids? Also, programming is very new to me-can you explain the features/benefits in regards to 4.6/5.4 Ford engines? Again, thanks in advance.
