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.
