This air filter is heavy duty like the truck. No cheap, thin, or flimsy filter here! I am a Docs diesel customer now!
Thank you the quality and prompt shipping of my filter. Keep up the great work.
Perfect fit and great quality, no issues after installing.
Initially I was a little fearful of not putting in a Mopar or Fleetguard air filter in in fear of collapse. I’ve been using Docs for approx. 60,000 miles with no issues at all, soon will be switching to fuel filters.
Perfect fit and works great.
Perfect fit, no glue strips, no errors codes and great quality. Will definitely buy again!
Their great products and cheap enough I change all my filters at every oil change. Thanks for a great product that is affordable.
Ordered the complete filter change out pack(fuel/separator, air, and cabin air ). Quick shipping, and the quality is top notch. Been using OEM, and the only difference I could tell would be that the Doc's filters were clean! That, and they cost a lot less than OEM. Also, past air filter changes on the 24 Ram 3500 without using OEM resulted in the truck throwing DPF codes. No codes woth the Doc's filters. Well done, guys. Will be ordering again soon.
The experience was great. I’ll be buying my filters from Docs going forward.
Great experience and top notch filters delivered. Fit and performs perfect! Customer for life as long as I own a diesel!
