TPC0001 is a charge air cooler for Peterbilt trucks, model years 1992 to 2009.
The core measures 33.5" high by 30.625" wide, 2" deep. It has a 4" inlet and a 4" outlet.
It replaces 61 OEM and aftermarket numbers, among them CAC100, 0518730L, 0706657A. 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.
