No Glue Strips. Stronger Paper. OEM Level Performance.
If you picked up one of our 6.7L Cummins Air Filters and noticed the new look with no glue strips and a tougher, more rigid paper media, you might be wondering what changed. At Doc’s Diesel, we stay locked in on one goal: delivering filters that meet or beat OEM performance every time. This update follows the same direction the OEM Mopar filter took for 2019 to 2025 RAM 6.7L Cummins trucks, so your truck gets the latest design built for real-world diesel use.
OEM suppliers moved away from glue strip construction in recent model years and went with a stronger, self-supporting filter media. The idea is simple. By removing glue, you remove the chance of adhesive breaking down under heat, humidity, or long service life of your air filter. You also open up the airflow because there is no glue seam blocking anything. The new media design gives the air filter more strength so it can hold its shape under serious load. We reverse-engineered the updated OEM design and matched it with our own improvements, so you get an air filter built for work, not for show.
What Changed with the Updated Doc's Diesel Air Filter?
Our old Cummins 6.7 air filter design used glue between the pleats. The upgraded version removes it entirely. The paper media used to be standard density. Now it is higher strength and more rigid. Instead of relying on glue for structure, the new pleats are self-supporting and more uniform. The fit and function now sit nearly identical to the latest Mopar design, except ours is built with even more consistency in the media durability.
This tougher air filter media stays solid under heavy airflow pressure, along with temperature swings and vibration. With no glue acting as a weak point, you get smoother airflow, stronger air filtration efficiency, and fewer chances for anything to fail down the road.
Engineered for Diesel Performance Same Fit Stronger Build
Even with the new air filter design changes, your install stays the same. The filter drops right into every 2019 to 2025 RAM 6.7L Cummins airbox with no fuss. It delivers verified 99.25 percent efficiency based on ISO 5011 testing. It holds 344 grams of dust, meeting or beating OEM specs.
The rigid high-density media is built to stay in shape and not collapse over time. It may look new, but it is the same trusted Doc's Diesel protection built to keep your engine breathing clean and steady.
Why This Update Matters for Every Diesel Owner
If you take pride in caring for your Cummins, the design change pays off. The tougher paper lasts longer and resists collapse and clogging. The no-glue construction air filter removes one more failure point in a hot and humid engine bay. The engineering follows the OEM direction, so you know your filter is built to the same standard your truck expects.
Whether you tow daily, drive, or work your truck hard, this upgrade keeps your airflow clean and dependable. The new 6.7L Cummins air filter from Doc's Diesel is available now in our filter combo kits and maintenance bundles. Ready whenever your truck is.
