I just took delivery of my 07 Screw, and decided to get the 3.5" AF1 put on tonight. The install went perfectly until I got to the portion of installing the locking screw in the heat shield (the one with the blue isolation piece.) It appears from the picture in the directions there is a ledge on the fender for this to engage into. On my truck it appears this ledge is not there (maybe a design change?) Has anyone run into this? I am not above fabricating my own bracket for an attachment point, but I wondered if there was a simpler solution. I am going to look at a co-workers 04' tommarow to see if I can figure out the difference.

 

Wondering the same thing. Did you find a solution?

 

hmm.. trussell, I just installed the 3" AF1 on my '05 Screw a couple weeks ago and you're right, there was a place for that screw to connect on mine.. I think it'd be an easy fab to make a bracket if it's not there on yours, but I'd sure think they'd have designed it right for your '07, I'd hope!

 

The K&N intake kit goes into detail about that little difference between the 05's and the 07's. Are you sure yours didn't come with some literature regarding that issue?

 

The only resolution I got was to fabricate my own bracket. I made it out of 1"x5"x1/4" stock. Tapped it for the AF1 6mm bolt and screwed it to the fender with a short automotive style self tapping screw. I ended up using a couple of washers to get the elevation perfect to support the heat sheild. If I had more time I would probably heat it and make a small offset, so I did not need the washers. It's mostly covered by the heatsheild, and hardly noticiable to the causual observer.

 

trussell, did you take pics?

 

I just bought a used AF1 with no directions for my 07 FX2 5.4 can you send some pics.of your install.
Thanks

 

Humm, I was considering the AF1 for my 07. I'm mechanically inclined enough to fabricate a bracket, but shouldnt have to on a $300 part.

 

I just put an AF1 on my 07 FX2 and did not have to fab anything the nut was right in the frnder where it belonged.

 

gunny think i have seen that truck running around town... really nice

 

I agree 110%. You expect to have to make minor modifications on a cheap intake, not a $300+ AF1.
