TUC0004 is a charge air cooler for the Ford A/L9000, L7000, L8000, model years 1993 to 1998.
The core measures 32.25" high by 25.5625" wide, 2.25" deep. It has a 3.5" inlet and a 3" outlet.
It replaces 17 OEM and aftermarket numbers, among them CAC125, 1003304, 1003306. Searching any one of them will find this part.
On charge air coolers the inlet and outlet positions and the boot diameters matter as much as the core. A cooler that fits the opening but presents its connections on the wrong side will not plumb up.
