TPC0013 is a charge air cooler for Peterbilt, Kenworth trucks.
The core measures 27.5" high by 23.5" wide, 1.9375" deep. It has a 0" inlet and a 0" outlet. There is no integral oil cooler and no filler neck.
It replaces 33 OEM and aftermarket numbers, among them PET17704, BTC1090, BT1090. 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.
