Engine components is a very broad term. What HSP Diesel means is anything essential to your engine working. These can be valve covers, thermostat housing, coolant bypass, coolant filters, oil filters, coolant tanks, exhaust downpipes, or even the coolant tube. All these pieces are necessary in good working order to have a well-running engine that won't leave you stranded on the side of the road.

We know some engines are slightly more sensitive to issues. The 6.0 Powerstroke is one of those engines because of its high-pressure oil-driven injectors. Then we dive into engines like the 5.9 Cummins that pretty much runs on anything. No matter your flavor HSP Diesel has parts that are going to be made to give you the best possible outcome for your engine.
