TPC0006 is a charge air cooler for the Peterbilt 320, model years 1993 to 2006.
The core measures 35.75" high by 29.375" wide, 2.5" deep. It has a 3" inlet and a 4" outlet.
It replaces 37 OEM and aftermarket numbers, among them CAC091B, 0518005, 0518005EXCH. 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.
