TMC0016 is a filler neck: charge air cooler for Mack trucks.
The core measures 40.875" high by 8.8125" wide, 4.5" deep. It has a 0" inlet and a 0" outlet. There is no integral oil cooler and no filler neck.
It replaces 2 OEM and aftermarket numbers, among them 280120, 280120N. 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.
