This STC fitting is a recommended update for all Powerstroke 6.0 from 2004-2007.
The old style fiiting was prone to leak, causing hard starts, low HPOP pressures and engine stalls after reaching normal operating temperature.
Updating this part is Highly recommended when you are replacing your EGR cooler and/or oil cooler.
