Sorry if you read this on post on my F150 thread, I thought it might get more views here.
I was doing some reading on these things (in a quest for better mpg's) and came across a very interesting mod. The factory intake has a snorkel thing on it with a diameter of maybe 2 inches. The mod is to remove that restriction and add a 3 inch piece on there. So, I used a 3 inch rubber coupling, and a piece of 3 inch PVC pipe, about 3.5 inches long.
Note: I know this will work on the 4.6 and the 5.4, but I'm not sure on the 4.2 V6.
Here's the factory unit
Comparison with the new piece, you can see the extreme difference in size
I had to use about 1 inch of the factory snorkel to get a secure clamp, I failed to take a photo of it. But basically, I cut an inch off and it's under the clamp on the coupling.
I also had to taper the end of the PVC to fit it into the hole in the fender well
Showing the fit into the fender well
Project complete
I will report back with more info. I filled it up right before I did the mod. I got a measly 13.5 mpg last tank =(.
