TPC0004 is a charge air cooler for the Peterbilt 330, 385, 387, model years 2000 to 2006.
The core measures 25.875" high by 19.125" wide, 3.125" deep. It has a 4" inlet and a 4" outlet.
It replaces 43 OEM and aftermarket numbers, among them CAC087, 1E4580, 1E4955. 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.
