Quality filter
Perfect fit for my 19 6.7 Cummins. Good quality and are exact oem size. Won’t do anything else than these. Also got the crankcase filter as well

2020 Ram Cummins
This is the second time I've ordered and installed it. It fits perfectly, and there are no performance issues at all. I will definitely recommend it to save yourself a buck or two.

Great
Price is great. Used on 2021 Ram 2500 with Cummins. Fit perfectly. Dealer charges 400 for this service. Only took about 30 minutes saved a lot of money.

Looks good
This is good quality filters, but I don’t know how it would work with RAM2500 diesel because RAM is sensitive and only Mopar brand fits right , but wanted to give a try. I will update my review in a week

As good as OEM
I was cautious to move away from factory filters, however I think these run just as well if not better. I’ve had 0 problems with these filters. The only suggestion I could add is maybe ship the box sealed, or place the O rings in a separate bag so they don’t fall out of the box while shipping.
