DOC'S DIESEL
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.

1st time buyer
I have told so many of my friends about your products and go affordable they were if you want to service their own vehicle . You filters fit just like the oem filters fit the only thing I didn’t do myself was change the oil I took it to the dealership and took your filter they questioned it a little but went ahead and used and service wasn’t $350.00. Thanks.
