 I replaced the air filter on my 2011 Jeep Grand Cherokee Limited with a K&N filter and immediately noticed a difference in acceleration and power, especially going up the steep hill to my house. I would recommend this to anyone.

 It is like a ( Breathe Right nasal strip) for your jeep. 2011 Jeep Grand Cherokee, 5.7L V8 HEMI. Just enough more airflow for an increase in throttle response (performance). I see better fuel economy over the very thick stock factory air filter. Seems to shift smoother, faster with the K&N filter. I can not think of anything else for the money that gives you the return that this air filter gives. In my old 97 and 99 stock Cherokees 6 cylinders in Leadville,Co at 13,000+ feet there was one trail and at the end was a hard climb ( Had to use full throttle ) where the stock Jeeps with the K&N air filters would give you just enough more air flow ( where the air was very very thin or a lack of it ) a really nice advantage over the Cherokees 6 cylinders with the stock air filters. It sounded like the engine sound where it was sucking air was in slow motion. (The lack of air would just rob the jeep of any horsepower and it felt like you were moving in slow motion also.) But the ones with the K&N filters would make it to the top. This will always stick in my memory... Thanks for reading.
