Mr Troyer
Just wanted to ask do you see any fitting issues with using the air force one cold induction kit. I have talked to about 5 guys who have 03 HD they said that it (fitting) was a problem. I think they tried to do it themselves, I'm going to have mine installed at a shop. Thanks

Hi Dex,
No, we don't have any problems installing the Air Force One intake kit on the factory-supercharged 5.4's - it's the exact same air intake tract and the same AF1 kit on the Lightning as is on the supercharged Harley - the supercharged 5.4's are all the same in that regard.
However, for those who also order the additional AF1 S/S extension that replaces the factory convoluted rubber throttle body boot on those supercharged 5.4's - now with that piece it *does* take a bit more time & more work to carefully align the new air intake tract when installing as compared to just doing the basic AF1 intake kit *without* that S/S extension. That piece is optional, not standard on the Air Force One intake on those supercharged 5.4's, so my answer is different depending on whether you ordered it or not.
When I installed my very first one (meaning the optional S/S extension), I pulled too much of that extension out of it's "boot" on one end - the piece on each end of it that is plastic or synthetic cooling hose material in either blue or black color - anyway, because I had pulled too much of the stainless piece from the boot (pulling the boot too far off the extension), I had it come apart on me the first time. But that was very obvious of course, and a very easy thing to correct - it's just a matter of being careful with the installation, making sure that you leave enough of the stainless extension inside the "boots" on each end.
The issue is having enough "room" for when the engine moves, as the motor will "torque over" under heavy throttle slightly, rocking just a little bit sideways on it's motor mounts - we generally recommend having somewhere around 5/8 to maybe 3/4" of the stainless extension on each end covered by the boot on each end - that generally gives you plenty of length, allows for slight engine movement, and it all stays together neatly & properly.
In other words, it's just a common sense kinda thing, and that applies no matter whether you install or or a shop installs it - in either case, the person (whether it's you or a mechanic) has usually not installed this exact part on a supercharged 5.4 before, so it's still usually a first-time situation - so even a good mechanic needs to take that into consideration.
Almost all of our customers install it themselves, it doesn't require a mechanic- just someone who pays attention to the details, basically.
Good luck!
