K&N Performance Diesel High-Flow Lifetime Engine Air Filter: Increase Power: Premium, Washable: Compatible with 2013-2026 RAM: 2500, 3500, 4500, 5500, 33-5005

Easy to install. Perfect fit. Never need to purchase another filter saves money over the life of vehicle. Clean as instructed. Noticed an increase in fuel millage.

Can't go wrong with a K&N. With proper care and maintenance, this filter will outcast most vehicles. Power increase claims seem bogus to me. At most, throttle response may be improved some.

Same as usual. I have this air filter on all of my vehicles. Very good product.

After installing in my 2025 Ram 2500 6.7Liter Cumins powered truck is averaging over 20 miles to the gallon after 9000 miles.

I got this cabin air filter to help with alegeries and to keep the cab air clean works perfect for both of those. It fit a 2020 ram powerwagon 2500 it should fit other models. It's easy to install and easy to clean. I would recommend a cleaning and oiling kit.

I had changed out my filter and noticed a huge increase in DPF Regen cycles, about every 30 miles. Did some reading and found that some trucks don’t work well with the filters that have the glue strips holding the pleats. These filters can collapse and cause restrictive air flow which increases soot. I also read that some Cummins don’t like the K&N filters, either. They will throw a CEL for underboost. I put mine in this morning and just finished an hour and a half drive. Truck immediately went into Regen (it was already at 50% when I put the filter in). I noticed a 2-3 mpg increase on the fuel use indicator, less lag in engine response going from a stop to moving at about 10mph. And absolutely no climb in the DPF full indicator. Still no CEL at this point. Seems like the Cummins may be hit and miss with the air filters. Some like the paper elements with the glue strips, some like the K&N. Edit: After driving a while, my truck did start regenning, again. Not as often as before, but still way more than it should be doing. Ended up hunting down a MOPAR filter and was able to go from 30 miles per regen with Doc’s, to 95-110 miles with K&N, and MOPAR is getting 250. Still more than double normal intervals that should be expected, but way better than before. My conclusion is that unless you tune for a different filter, you’ll see problems with the 5th gen Cummins.

My former profession was an Accounts Payable Auditor for the phone company. Here's my documented facts so far. Was able to document a (1.9 & 2.2) MPG increase in diesel fuel mileage after installing my K&N Air filter into my deleted 2013 Ram 3500 dually truck. Price of diesel has changed from $1.89/gal on 4-24-20 to now costing me $5.45/gal on 2-24-23. I have the receipts showing the price paid per gallon since 1-28-20. They're loaded into an Excel spreadsheet documenting my travels to 23 states (post retirement) collecting travel fuel receipts towing my 5th wheel. Excel doesn't lie or deceive. I like facts, not manipulative marketing pitches, glossy brochures, nor any baloney. I was raised in the "Show Me" state called Missouri. These are the questions I had to get answers to for my comfort spending $119.99 on this part: - Did I want to save money on my fuel costs? - Did I want to quit buying air filters? - Definitely wanted to help my truck breath. - Would this purchase accomplish these? Yes..... check! Well, I finally got those questions answered and I purchased my K&N 33-5005 filter on 1-24-2023. Wish I had in January 2020 when I bought the truck. Now it's your choice. You decide, what you know is best for you. HawKeye

I have a 2019 Ram 3500 diesel. I put on the K&N filter and my mileage went from 14.5 a gallon to 13.3. Worse than that, I got a check engine light after only one week, my first check engine light ever, truck only has 62,000 miles on it. I replaced it with a paper filter, reset the engine light code and sent the K&N filter back, I haven’t gotten a check engine light in last two weeks. In fact, MPG is now 15.0. Think I will start changing filter more often now, like every 6 months now. Don’t get me wrong, I really wanted the K& N to work unfortunately, my truck is just too particular on the airflow apparently.

Fits perfectly

Perfect fit exactly as described. Price may have been a little more than you would pay directly from K & N but shipping is probably more. So I think you are a head of the game ordering from Amazon

quicker response when hittin the gas and a bit more power

This filter is great it lets more cool air through and when is gets dirty you wash it out let it dry and then you re oil the filter nd put it back in

Installed on 2019 Ram 2500, went across Canada to the Rockies towing a 35 ft trailer. Filter makes a difference when pushing the truck hard. Good purchase.
