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.
It was my first time doing the complete filters and Doc's made it so easy.Enter what you have and they send you all the right filters no hunting around different store finding the right ones, so simple looking forward to doing the wife's truck, and it's all quality stuff, thank you Doc's will definitely be using you from now on, 5*
same as any I've bought recently .
All items in my kit were exact fit
