Premium filter
Great filter. Fits perfectly. Looks great, like a very high quality filter. Breathes a little better than with the original filter and supposed to filter as well is the original. I will probably buy this filter for all my vehicles

Great filter exactly same size and fitmint like OEM . Had K/N filter in the past on my other vehicle and have been slacking on getting one for my 2015 Durango. Better throttle response , easy installation

Great filter...thank you K $ N!
I waited a while to review this air filter because I was skeptical of all the claims in the reviews. I have had it installed in my Dodge Durango for more than two weeks now and can honestly say it does make a significant difference. I have a mileage calculator in my vehicle. In the 6 years I have owned the vehicle, it rarely averaged above 18.7 mpg in town. Since installing the filter, I have been driving the same route that I always have. I made sure that I drove it long enough that I wasn’t thinking about how I drove. That way I could contribute the improvement in efficiency to the filter and not how I was driving. I am now consistently averaging 19.5 to 19.7 mpg. 1 mpg may not seem like much, but if you drive an SUV or truck, it is significant. It also gives me peace of mind knowing my 130,000 mile engine is running more efficiently and achieving less wear and tear as it gets older. Thank you K & N! Great filter and worth the extra costs

Good filter and does a much better job over stock
Noticeable improvement of airflow and fuel economy stayed the same despite driving slightly uphill for about 6 hours- so it’s definitely helping remove a bit of restriction. Fits perfect, doesn’t smell like oil, and is a quality filter. I’m not really into washing filters so I don’t like permanent units

One of the first "upgrades" I make to all my cars!
I've been using K&N airfilters for 40+ years now...Street cars, off road cars, stock intakes, CAI aftermarkets, commuter vehicles. All my vehicles for the last 40 years have had K&N filters. And the funny thing is that I'm only on my second clean/oil kit! And that's barely used. So of course, when I purchased my used 2012 Overland Grand Cherokee with the 5.7L Hemi, I had to get ah K&N. I want this vehicle to be stock, so I got the filter to fit the stock airbox. Now I'm good for a few years without having to worry about my airfilter...take *THAT* Jiffy Lube! Trying to charge me $50 for a paper sub-standard airfilter...I got a K&N for basically the same price!
