DAM how the hell do you get 20 MPG???? Is that all highway? What do you get in the city? I do about 80-85% city and I get 12 MPG... I drove highway home when I bought the truck and I got about 16-17 MPG... I dotn really horse the engine either...

 

I just got 20.03 MPG on a return trip from Bristol, Tenn to Eastern North Carolina on Monday and then drove around thru the city(484) Miles for the rest of the week. I filled up on Friday and it took 24.1 Gals I was getting almost 21.5 during the drive though. Just the daily drive to work every morning takes it toll less than 5 Miles to work.

 

Oh' yea

05 F150, 4.6l, 4X4 Auto 3.55 gears Supercab no Mods other than Vortex Bedliner.

 

Simply Genius Idea!!! Now my truck sounds like my old 4.0 v6 ranger 4x4 with 3" holes drilled in the airbox... Sounds aggresive!! Cant wait for the K&N drop in and magnaflow set up, will really sound sweet!

 

I have 04 F150 XLT 4.6L 4x4 AUTO Reg Cab.. how do I figure out what gears I have? The best I have had was 16-17 MPG on the way home from picking up the truck...

 

what a easy mod took no more than 5 minutes, sounds a little more aggressive at wot, throttle response is better , thanks for the idea , freebie

 

The link doesn't work. Really interested in what to do for the 5.4

 

Yes, this is mostly highway mpg. but some city driving in and around Roswell/Kennesaw, Ga. I think with the tonneau and having the 4.6 with 3.55's also reg. cab makes truck lighter and more aerodynamic or something maybe. I'm just glad it's like that.

 

How do you disconnect that hose that runs to the "L" tube or the elbow the runs to the TB?

 

there is a clamp on either side of the L part that you just unscrew to loosen and then just pull it off and then there is the hose that connects to the back. there is a green lever that you push to the side and it disconnects easily.

 

Just took the air silencer out today. I sware by the the seat of my pants (no dyno) I have an improved bottom end response. Thanks Guys.

 

Did this tonite on my 01 4.6L, everything worked great, but boy was that silencer hard to get out. Definetly can feel better throttle response.

 

I like that it sounds like an intake system already... I am puttin a K&N Drop in soon so it should sound even better!! Yeah, I think I used channel locks, plyers and a screwdriver to pry that sucker outta there... 10 minute mod!!! Love it!!

 

I'm glad to see alot of 4.6 owners doing this.

 

Just did this mod on my 2006 SuperCab XLT. I don't know if it's just the sound giving the perception, but, it does feel like it made a difference!

Thanks for posting this info!
