TKC0011 is a charge air cooler for the Kenworth T800, model year 2007.
The core measures 46.375" high by 30.875" wide, 2.5" deep. It has a 4" inlet and a 4" outlet.
It replaces 11 OEM and aftermarket numbers, among them CAC333, R1292001, X4997001. 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.
