4031000H | Mack MP8 Holset HE431VE Turbocharger (Actuator Included), New

If you're lagging up the hill or wondering where all your boost went, its time to replace that turbocharger. Whenever replacing your turbo always make sure to change your engine oil/filter and air filter after installing the turbo, properly clean your boost tubes and intercooler to avoid catastrophic engine damage, check and replace your cracked or worn boost hoses and tubes, and remove caps or plugs that may have been placed in the oil drain or supply during assembly. While a turbocharger is an item that can simply fail due to age and use, there are a number of outside issues that can lead to turbo failure. Some of the causes for this are poor/improper maintenance, intake/exhaust restrictions or intake/exhaust leaks; make sure you get to the root cause before firing up that engine again!
