TKC0014 is a charge air cooler for the Kenworth T600, T800, model years 2005 to 2007.
The core measures 30.875" high by 14" wide, 4.25" deep. It has a 4" inlet and a 4" outlet.
It replaces 4 OEM and aftermarket numbers, among them CAC112E, 1E0051640000, 1E5164. 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.
