Function of this part

The aftertreatment system treats exhaust gases after they leave the engine using components such as the DOC, DPF, and SCR catalyst. It controls soot and NOx emissions by trapping particulates and converting harmful gases into less harmful compounds.

Why this part matters

These components are central to emissions compliance on modern diesel trucks. Problems in the aftertreatment system can cause frequent regens, power derates, and down-time until the fault is corrected.

About the brand

Cummins engine parts are trusted for reliable power in a variety of heavy-duty truck and equipment applications.

Fitment & usage

Used OEM parts are a smart choice for controlling repair costs while still using original-equipment components. Always match the OEM part number(s) listed to your existing part, and consult your service manual, dealer, or technician if you are unsure about fitment.

Note: Because this is a used component, normal signs of wear such as scratches, discoloration, or light surface corrosion may be present. Refer to the product photos and information on Second Truck Parts for the best representation of the part you will receive.

Best air flow
Size: 9.6" x 11.1" x 2.2"
I have a 2022 ram 1500 four-door. The factory filter from the ram dealer is about $40 but it’s not reusable. That was the only one I found that had good airflow into the cabin. I tried several other brands but the airflow was reduced excessively. The ram filter was 15 mph, most of the other aftermarkets dropped the airflow to about 9 mph. I just installed a K&N reusable filter and the airflow is back up to 15 mph. Great job K&N!!

Fits Well and Reusable. I'm Happy.

For less than the price of 2 disposable FRAM CV11671 cabin filters for my 2019 RAM 1500 and this will last forever. If it gets wet, like I've had happen with the paper throw-away filters due to stuff falling off trees in the spring and clogging cowl area water drains and backing up into filter ( yeah, that's a thing ) and can clean and dry this filter and reuse. Great directions came in the box along with a sticker to point out that this is a lifetime filter so someone doesn't throw it away. Do this yourself. Don't let some auto repair shop talk you into it. I was getting tires balanced recently and heard a quote they gave over the phone of $79 to do this. I don't know what kind of vehicle that was for but this ain't rocket science. Don't get ripped off. Now back to this filter. There is no arrow for air flow so I figure it flows well both ways and just put it in with the K and N logo right side up and facing out. It's not a straight in shot the way RAM positioned the opening for the cabin filter slot but was no big deal. Also realize this isn't a perfect square filter ...It's a rectangle so don't try to shove the fat end in and say it doesn't fit. I haven't noticed any air flow differences with the heating / ac system but some people say they do. I'm just happy I don't have to buy anymore disposable filters and can dry this if it gets wet. The cleaning and refresh spray kit is #99-6000 that comes with a 8oz and 12oz bottle and I'm trying to find that cheaper somewhere for when I do clean this thing.

Can’t go wrong with K&N
Size: 9.6" x 11.1" x 2.2"
So I recently took my pickup in to have some recall work done, half way through the process I got a call from the dealership stating I needed a new air filter and that a new one would cost nearly $60. I chuckled and told then to put the old one back in and I immediately came to Amazon and ordered this cabin filter. I’ve used K&N products in the past and have never been sorry, and that is the case with this lifetime filter. Upon installing this filter I noticed an IMMEDIATE difference in air flow into the cabin, it even smelled better. If this filter ever gets dirty Ira easy to clean and reinstall, paying for itself over time. Do yourself a favor and pick one of these up, you will not be sorry.
