Use the K&N Performance Gold Oil Filter HP-4003 to protect the engine on your Dodge 5.9L/6.7L Diesel. K&N Performance Gold Oil Filters for automotive and marine applications have been constructed from the ground up to satisfy the high performance needs of race car owners and drivers, as well as the average vehicle or boat owner who wants the very best oil filter available. The heavy-duty construction provides strength to reduce the possibility of bursts and helps reduce the risk of rock and stone damage. A Sturdy 1" wrench nut makes removal quick and easy. The filter's inner filter element traps contaminant as small as 10 to 20 microns in size. The solid construction allows for oil flow rates between 12-16 gpm (depending on filter size), and is unaffected by racing fuels.

Very satisfied
I have used these filters for years on my 04 Ram 2500 and are very happy with their performance. I do change the oil sooner than the mfg recommends but figure it's a small price to keep the Cummins in good shape.
low flow
i was using oem mopar filters with ams oil, no problems with oil pressure coming up in any condition. I switched over to the k&n filter and i noticed a loss in start up oil pressure and idle oil pressure. THE FILTER IS TOO RESTRICTIVE. I'm using oem and changing it twice with my ams oil.
