I installed the EFH™-DM1R0750 filter conversion on my 2017 Chevrolet 2500HD with 40,000 miles. I have just under 10K miles since the installation and it has worked perfectly without any problems. I loved how easy the install was, it literally took less than 30 minutes and that was laying on a roller creeper on the floor. The ability to change the larger external filter is a game changer in a time of need. I would rate this product a 10 out of 10.
