I have installed the AIS II on my '01 and just read the new article (07/15/06) on the same install.

A couple of comments/questions I would like to make regarding the article and the install.

The comment is that if you have an aftermarket cooler (I have a Banks), the inlet tube will not install unless you cut about 1/2 inch off of the tube that goes through the radiator support. After cutting, there will still be about 3/8 of an inch sticking through. After this install, I also noticed that the air traveling to the inlet tube comes up from above the bumper. This seems to defeat the purpose of the install. I am thinking of making an adapter plate that will run from the core support to the headlamp mounting panel and cutting out the area in the headlamp mounting panel to allow the air a direct path. It looks like it will flow from the left side vent in the grille that is usless at the moment, more like a ram air. I am planning on screening the inlet and maybe putting some sort of a water deflector in it. This would appear to let the cooler outside air in, without the heat from the radiator and cooler.

Anybody have any ideas on this.

The question I have is with the foam intake used to get air from the fender. Where is the air coming from first and would this air be contaminated from dust coming from the wheel?

I have noticed that right after the install and doing a couple of WOT's, the filter minder was pulled to the 1/4 mark with the new filter. In doing the same test without the filter, it did the same thing as stated in the article, so I agree that there is still a restriction.

I just dropped $200.00 for the AIS II and was not planning on spending any more cash on the intake air. Looks like I will be spending another $30.00 to make one of "Fords Better Ideas" better.

 

I am not sure why you needed to trim the snorkel of the AIS because of a Banks aftercooler. We have installed many of these and never seen a need to trim the snorkel because of the aftercooler. Some times we trim the snorkel to allow a little more clearance for air flow behind the deflector.

Regarding the fender sleeve. The opening is above the inner fender liner, so most of the air in that loaction comes between the bumper and head light areas. We are the designers and manufacturer of the foam sleeve and I have them on our 2001 Superduty and Excursion. You will see dirt on the filter from this opening, but it is not any more excessive than the dirt being filtered that comes from the snorkel.

 

I had to trim the tube as the flange would not go past the cooler into the radiator support. The Banks cooler has much bigger side tanks than the OEM. The Banks cooler actually covers part of the radiator support opening. It took a while to figure out what was wrong. I even tried it without it being connected to the filter box lid. It just would not go through, but the trim did not affect anything, but it was a PITA to install.

At this point, I am just going to leave it as is until I get the next two mods completed. Installing the gauges and the tee to fool the boost sensor.

I guess that I do need to do the foam mod before I go see Jody so he can properly code the six position chip that I want.
