On a 2003 6.0L Powerstroke, the Injection Pressure Regulator (IPR) valve—such as the Sinister Diesel Injection Pressure Regulator Valve (IPR) for 2003-2004 Ford Powerstroke 6.0L—is located at the rear of the engine block, driver’s side, behind the turbo and beneath the Y-pipe. The 2003 6.0 Powerstroke IPR valve is threaded horizontally into the high-pressure oil pump (HPOP) cover.
