The power and performance abilities of a big truck have as much to do with internal parts as sheer size. When it comes to the power stroke diesel, proper operation of even the smallest IPR valve is essential for that power and performance to come through. Short for injection pressure regulator, an IPR valve serves a vital function within a power stroke engine, controlling the rate that high-pressure oil reaches the engine according to the specific characteristics of its injectors. The IPR valve entered the market at the same time as the 7.3-liter power stroke engine, 1994, and has remained largely unchanged in structure and function since then, though its exact size and configuration is unique to each engine or vehicle that uses it. Although generally a reliable part, the presence of debris within the valve or a blown O-ring can cause it to malfunction. In this case, removing and servicing, sometimes completely replacing the IPR valve, is essential. It is easy to find the proper valve for your engine among the large inventory on eBay. The engine power of a big truck, be it a full-size pickup, SUV, or commercial vehicle, is a critical part of its performance package. Make sure that even the smallest valves are ready to fire in all the right ways to deliver that performance when you need it most.
