Fuel filter were great, all filters seemed to be made well however the oil filter did not fit. The dirty filter pictured is motorcraft.
Got my two sets of filters as ordered and then on the next day received a phone call from Trevor advising me that I was the winner of the 2025 Dodge Ram Truck drawing. Unbelievable, still having a hard time processing the whole thing. Looks like I will be buying filters for a Dodge Ram as well as a Ford Powerstroke. Thanks Doc's!
Ecellent And Prompt"😊
High quality OEM filters, delivered fast.
Filters look like they're high quality I have tried the fuel filter. I'll find out in a couple of months how they look and how they perform. So far very happy
Its just a filter , they fit
Shipping was fast. Filters are Chinese imports. Don’t know if I will use them or not.
Hey Mark! Thank you for reaching out. Our products are rigorously tested by SGS (the world’s leading inspection and certification company) and inspected to meet OEM Micron and efficiency ratings. Every filter in our lineup is engineered to meet or exceed OEM standards.Thank you!
I’ve only ran Ford OEM filters and do the maintenance myself. I decided I didn’t want to spend 70 plus dollars on ford and went this direction. Was a little skeptical at first with the fuel filters because if they don’t have the right seal then the system doesn’t prime well. I will say, after bleeding the system like normal, the truck fired up and has ran great! The oil filter is the correct size and all the o-rings fit their caps great. I will purchase another set when it’s time!
every thing was spot on as usually!!!!!!
I always use doc's
