On the 04+5.4's it's actually called the DWV intake mod. Here's what it is.
I took it for a short 10 mile cruise and didn't really notice much in acceleration or any intake noise. In fact it may be quieter than stock. One thing I noticed is at a stop in gear the idle will float around 520 where as it was floating at 530 before. The rig also felt like it was smoother running at idle. Hopefully maybe it might help my gas mileage a little. I custom tuned lvl 3 on the Edge 2 weeks ago and have been running 93octane and seeing 16-17mpg's. When I had it custom tuned on lvl2 on 87 I was seeing 14.5-15.5. Here are some pics of my $11 intake mod
Stock pipe next to my replacement which is 2' PVC 3"diameter and a flexible 3"-2"adapter. I ended up cutting the pipe to 10"
new piece painted and installed

Fully flexed the accordion pipe, there's noway it's coming out of the fender.
Now I need to clean the rest of the bay up!
So far I have not seen any gain in MPG's I'm getting about 16.5. I have the 27.5g tank and the low fuel light comes on around 375miles on the trip. I'm also running the Edge W/custom setting's on lvl 3 with 93octane. My rig is an 05XLT 5.4, 3.73, single straight piped

why did you use a 3 to 2 adapter?? u can get a 3 in in the fender just needs to be sanded down to fit, thats almost the same as stock, put a 3in pipe in the fender and i bet youll notice some differnece i did, its more on the higher end of the rpm range, and my exhaust sounds better too it doesnt tapper off at the top of the rpms its loud all the way threw them now, im very pleased for 10 bucks
