FAQ'S

What Oshkosh models are compatible with your charge air coolers?
Our coolers are engineered to match the dimensions, airflow, and mounting layout for many Oshkosh heavy-duty and tactical vehicles, ensuring a precise replacement for OEM units.

What’s the difference between bar & plate and tube & fin cooler designs?
Bar & plate coolers offer more structural strength, better resistance to clogging, and superior thermal capacity in harsh environments. Tube & fin coolers are lighter, have excellent airflow, and are suited for standard-duty applications.

How do I choose the correct charge air cooler for my Oshkosh engine?
Compare your original cooler’s specs—core size, inlet/outlet orientation, pressure drop, and boost capacity—and select a matching unit using those parameters or the OEM part number.

Can I replace only the cooler without changing other system parts?
Yes, provided the hoses, clamps, and intercooler piping are still in good condition. However, replacing related parts simultaneously helps reduce potential leaks and ensures system integrity.

What symptoms indicate that my Oshkosh charge air cooler is failing?
Common warning signs include loss of boost pressure, decreased power, higher intake air temperatures, visible oil or coolant leaks, or damaged fins. Addressing these early helps restore performance and prevent engine damage.
