TKC0010 is a charge air cooler for the Kenworth, Peterbilt 330, T300, T800, model years 2003 to 2007.
The core measures 32.375" high by 9" wide, 4.25" deep. It has a 3.5" inlet and a 3.5" outlet.
It replaces 25 OEM and aftermarket numbers, among them CAC321, 1E0051450000, 1E5145. 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.
