This listing is for an OEM air box from a 1999 Ford F-350 Super Duty which I removed about 15 years ago to run an aftermarket unit. This should be original to 1999 2000 2001 and I think 2002 and 2003 Ford F250 F350 F450 F550 Super Duty as well as Excursion with the 7.3 Powerstroke diesel engine. 

Please verify fitment prior to purchase.

It's mostly complete but missing the plastic piece that fits over the battery. 

Condition:

Above average condition for being a 25 year old plastic piece. There are some scuffs and scratches present as well as a little bit of dirt left in the hard to find places. My son and I spent a couple hours cleaning it so it's drop in ready. 

One of the metal clips doesn't hold as tight as the other but you should be able to bend it a little to tighten it up. 

There is also a small rip/tear on the end of the rubber tube piece. It should mount fine as is. 

If you are restoring a 7.3 Super Duty this would be a nice original unit for you. 

30 day warranty if you are not happy with it.

Free shipping to lower 48 states! (it's not really free as I pay for it lol)
