Air Intake 89 E250?

Since they dont "make" specific air intake kits to replace the stock air cleaner box, does anyone know a vehicle intake kit that WILL work for a 1989 Ford E250 5.8 351? I'm not looking for anything crazy. We have the stock air cleaner box with a K&N filter and the whole box assembly is pretty junky so I want to replace with a better air intake kit. I dont want to spend a lot of money because I'm not looking for 11 second in the quarter mile. Just want a better intake. K&N intake kit would be cool. Again, just wondering if theres a different model car that has similar connections that will work with my van.
