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.
Filter set 6.4 powerstroke
Items were well packaged, and very well made. They arrived ahead of time and are worth every penny. Don't go cheap on quality to save a dime because rebuilding that engine is a lot more costly. I'll be purchasing these from docs from now on every scheduled service time. Thanks.
first time user
was very pleased with fast shipping and quality of filters will be purchasing again.
Positive so far
Ether fits with no leaks. Only time will tell on how they filter.
Thought I'd get all filters but I'm missing the separator filter!
Haven't used them yet.
Hi Matt! Did you check the DCS10263 box? Both fuel and water separator are in the package! We send them together. Let us know if you are still missing one!
