Cold Air Intake .

[kd4crs]

I'll contribute my personal experience with CAIs on the 04 and 06 F150 with the 5.4L engine. I had the 3in. AF1 on my 04 and it caused horrible drone as well as never ending check engine lights. The AF1 had to go. Next I tried the Outlaw Power intake on my 06 F150 for a couple of months and about 1,000 miles. I had no problems with it other than the intake resonance noise that it produces at certain RPMs. Unfortunately, it makes that noise constantly when towing our travel trailer so it had to go. Nice throttle response and I picked up about 1 MPG. Just couldn't put up with the noise. Some people like the noise, I didn't. Your mileage/results may vary. My personal conclusion is that after market CAIs on the NBS F150 are more trouble than they are worth. The stock intake IS a CAI and it is butt ugly but looks fine with the hood closed. The best modification I have found for it is the DWV intake mod I put together for my 04. It replaces the snorkel tip with a 3.5" piece of black ABS going into the stock fender hole for less restriction. I think Bill and I came up with this idea at about the same time so I can't claim I am the first person to think of it. It does work well and Bill has actually dynoed it and it has a gain of 7 or 8 ponies while still keeping the intake drone quiet. That and an AEM Dryflow replacement filter is what I roll with now.

Man, what a first post! I need a nap.

David,

Glad to have you here! Make yourself at home.

I think you're right... we both probably did the same mod at the same time. I never posted it because at the time I wasn't really big on the forum stuff (at least on the gassers) so you really deserve the credit for the original release of the modification.

The silly thing, as I understand it, is that you kinda got heckled for the original modification but then a year later Gotts came out with the same modification and now that's what everyone refers to it as. Unfortunately, we do too but only because I could find the DWV thread.

If you'd like, get me a write-up of the modification complete with pictures, and we'll put it in the technical section of the FAQs (which will be there soon... ) so people can see it. We'd like to see you get some credit for the modification as well.

Take it easy.

Thank you Bill, that is very gracious of you. I will put together a write-up with some pictures and send it to you so you can look it over and make any changes or additions you see fit before posting it. The original thread on another forum caused such a controversy that it turned into a nasty argument and I requested the forum administrator to delete it for the good of the site since it wasn't doing anyone any good. Subsequently, I deleted all pictures and references to it in order to let things calm down. I think you deserve credit for the DWV intake mod, though since you actually dynoed it. Before the original thread went away more than 50 people had tried it and to the best of my knowledge nobody ever got a CEL from it or had any other problems with it.

kd4crs,
I was fortunate enough to see your posting in that other Forum before it was deleted. Did that mod per your instructions a couple years back. Very easy and works well. Thanks.
