I've been putting off installing the AIS units since the battery tray for the driver side has been the issue. I bought a couple additional trays from a local salvage yard, but the way the AIS filter housing secures in place, it needs the flat tab on the end for securing it in place. So the tray needs to be flipped, which can't happen unless the 90* elbow bracket is taken loose and secured on the opposite side. I pulled the old oem filter housing out to mock up a modified battery tray.

I drilled out the 6 welds securing the two together...thought I wouldn't have to go all the way through, but it's necessary to get them apart. I mocked it up with the AIS unit in place, marked it, and will get it welded up and painted tomorrow.

I'm posting this to show an oem passenger side metal battery tray can be modified to work. This is important given if you can locate an AIS unit, they typically don't come with the battery tray that was provided with them when new...at least the 2 that I found didn't. I know there's alot of guys that take the factory plastic battery tray/filter box and cut it down to work, but I wanted to go this route for various reasons.


Welds to be drilled out for separation...


Six factory welds marked...


Mock up showing flat tab on opposite side for securing the AIS housing so passenger side tray/bracket need to be flipped to fit driver side...


Bracket welds drilled out and tray separated...

 

Nice write up and pics!

 

Was able to get the hardware, paint the tray assembly, and get it mocked up. I decided to go with a nut and bolt application rather than welding it up, which helps get the tray just in the right position for the optimum position. I still have one more hole to drill on the other end, but the two bolts you see in there now worked out to hit existing holes. So they are 5/16"x1" hex bolts with 5/16" flat washers either side, then a 5/16" lock washer and a 5/16" nut on the bottom...all galvanized. This will sure help the average Joe who can't weld...not that my welding is purdy...be able to do this. While I was at it I decided to do the secret zoodad while I was at it. I'm going to try this first and see how the stock...no holes cut...AIS box assembly works with the stock modified turbo. I'm thinking I'll have to either do the side fender mod or cut a hole in the bottom of the box...might look at another way once I get it in there. Will be interesting when I get this done on the F350 to move on to the wife's Excursion and do the same to see if the stock AIS box works on it since it given it's a stock turbo with the exception of the Riffraff 4+4 compressor wheel.

 

I have it up and running and so far it's all good. I was able to tweak the position of the snorkel the way it goes up into the front clip to keep it from rubbing and eventually put a hole in it. I still needed another bolt or 2 for the 3 attachments on the AIS unit given I have 2. So for future reference given these can't be salvaged from the factory setup if the AIS doesn't come with them, but your local parts store should have a flange bolt in the M6-1.0 x 35mm...I got mine at Home Depot where they have the specialty hardware when I picked up the 5/16" nuts, bolts, washers for the battery trays.

 

Nicely done.

I recalled reading this a while back and remembered that it was a good write up on the passenger side tray adapted for the AIS.

I’m currently lining up a battery tray in anticipation of an AIS being delivered on Friday.

 

Zoinks. Where did you source that baby?

 

Ahhh… there will be a reveal on Friday if it pans out.

 

If anyone is interested, I came across an AIS unit a couple days ago. It's located here in central Texas in the Boerne/Kerrville area. I sent him a message to see if the battery tray came with it, but he is still using it on his truck...probably went with an open element type filter. I can send a link to those interested if you send me a PM...I think he's asking a Benjamin for it...

 

I picked up my battery tray today from a local guy that parts out Superduties.

I think he wanted too much but I paid the $40.00 for it.

 

@bwguardian

do you recall if your battery tray once installed was on a slight angle.

Engine side is slightly forward of fender side.

Looking at the passenger side battery it appears to be the same. Engine side is slightly forward.

 

With the way I did it, there's adjustment to correct that in the way it bolts together.
