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.

Third time I used and only filters I will
Great made filters and great protection for my truck
I have been using Doc’s filters since I bought my truck new. The quality, pricing and service has been outstanding. I will continue to use them in the future.
Ram Filter Combo Set
A good price for the set. Usually can’t get all 4 filters at local auto parts store.
First Filter change
I found Doc’s on YouTube learning how to change the filters. After reading reviews, I ordered my first set. The price is great. The product quality is great. The website is easy to use and delivered in a few days. Couldn’t ask for more.
