The most common reason for turbo failure on the 6.4 Powerstroke is due to the original turbo actuator. The issue is so problematic that the original manufacturer, Borg Warner, has released a revised version to alleviate these issues. These are a retrofit and do not require the use of the cooling manifold. Kit includes installation instructions and all required hardware. This actuator does not require calibration, saving you a trip to the dealership.
