I was a bit skeptical as I’d read a lot of folks had problems with aftermarket filters for Ram trucks, but these worked just fine. Installed perfectly and no issues. Way more affordable than MOPAR.

I’m always worried about buying the MOPAR filters from Amazon because I’ve gotten a few Chinese knock offs. Decided to use Doc’s diesel this go round because of all the positive reviews and the price points. Well check back once it’s been installed.

Good quality filters. I returned mine as my truck doesn’t need the water separator.

Won’t know if they are as good as own until they are used.

To me these are as good as or even better than OEM filters for my truck. Easy to install. Very well packaged. Very quick shipping. Will def order again.
