Hey, does anyone know what kind of plastic the air intake box is made out of?

I've tried to glue mine twice, unsuccessfully. Finding a replacement has proven impossible (this is an e350).

Honestly just do a 6637 setup.
I think it was on this site was a long thread about air filter setups for vans.

1) it's been done. 2) hopefully not a k&n.
Here's another option.

The intake boxes are made out of polyethylene. It can't be glued, but you can heat fuse it. There are plastic welding rods available and with a heat gun you can weld it. Kind of like oxy-acetylene welding.

Generally, and on most of the Ford parts I've looked at, that information is molded into the part (for recyclers' use). There's a list of some common abbreviations near the top of this page:

I looked pretty hard. The top piece had no indication. Maybe the bottom half does somewhere, but it wasn't obvious.

Some other air intakes (from other vehicles) imply polypropylene so I bought some "GOOP" and will give that a try when it arrives. I'll probably have to preheat/anneal (whatever you want to call it) before applying it. In the meantime I've used packaging tape to patch it.

I tried plastic welding a different kind of plastic once with terrible results. The welding (using special welder which blows hot air) worked at first, but the plastic became brittle and snapped. I somehow doubt polypropylene would be any better but if the GOOP fails I'll be back in Oregon where I can have access to the plastic welder again.

Replacement unit is like $460

I prefer E6000, which is available clear or black.

That's not necessary for glue - read the packaging for the application temperature range.

From where? What brand? Have you checked local JYs, Amazon, & eBay for Ford/MotorCraft ones?

I don't think anyone is making them currently. The ones being sold are likely old stock hence the astronomical prices.

No local junkyards in five different cities had them.
