I used this filter to replace the [brand name] Filter on my [brand name] kit about 10 yrs ago. This particular size fits my 4.0l Rubicon and doesn't require oiling like the [brand name] filter requires. Also, my intake tube stays cleaner than with the [brand name] conical filter (with the [brand name] filter wrap) does, so I know it's doing a better job at protecting my engine. I take my Jeep off-road on a regular basis, so reliability is important. In the past 16 months, I have made a couple of long-range trips into Baja California, and across the Southwestern US all the way to Oklahoma and back to Southern California. Because I'm running 35 tires, I don't have an accurate mileage improvement to list, but you can hear the air blowing into the intake when you step on the 4.0l accellerator Great product that's Baja-proven (in my case).
Bought this filter to replace the oiled filter on my Brute Force Intake on my 2005 Hemi Ram 1500. The original filter was 8-years old and I wanted to try the DryFlow filter. The Brute Force has always performed well. I went to merge into traffic on the highway this morning and HELLO!,the HEMI has been re-awakened. Gas mileage is up 1.5 MPGs, too! I would highly recommend AEM products.
Very Happy with product and service :)
