Doc's Diesel Filters are spec'd and designed to meet or exceed the quality/performance of the original filters (OEM's) that come in your vehicle. Doc's premium grade media filter paper used on all Doc's Filters is what sets Doc's above the rest.
We wanted to go one step further in customer trust by providing,SAE J1985 3rd Party Testing of our parts.We did a full upstream and downstream efficiency testing along with a single pass efficiency test method. Our main fuel filters have been 3rd party tested, and as we get more testing we will be reporting the results.

So far so good. All filters fit. What else can I say?
2014 ram filters
Good experience everything on time
I just installed the above oil filter in my 3500 Ram 6.7 diesel. I do not have any experience yet since I just installed th filter.
I have been using doc's for a while. This is probably my 6th or 7th set. First they make it really easy to order and everything you need comes quickly. I hope this is a one off but my water separator filter lacked... the O ring was just wrong. Not painted and just overall just poor quality. It didn't want to thread up. Everything else was great as always. I will buy again I just hope this isn't going to become a norm. Only about 100 miles on this filter so we shall see.
