Great experience! Great price, fast shipping, filter was exact March to the factory filter, I’ll be changing some filters more often now that I’ve found Doc’s. Also never trust any dealership to change out you cabin air filter on your Ram 2500…..like I did. It was BLACK and filled with debris, so sliding in the brand new Doc’s filter felt extra special!!!
Fits tight and seams to be good quality
Filter does a great job. This is my third one I’ve ordered
Great products
I don’t think you can beat Docs when it comes to value and quality for your dollar. Will continue to buy from Docs
They came fast and at a very reasonable price. All well fitting.
awesome product and great turn time once ordered.

High quality material. I've been using these since the truck was new. No problems whatsoever.
It came in the filter package for my EcoDiesel. Definitely a higher quality item and it’s easy to install.
