Title: My first K & N air filter
Review: The item arrived yesterday. While it is way too early for me to tell you if it helps my mileage, I can tell you that I did feel an immediate difference in acceleration and smoothness to the engine. I drive a 2009 Jeep Patriot, which is a 4 cyl 2.0 engine. After reading about the filter on different forums, I thought at least I would have a filter I didn't have to worry about changing all the time. Installation was easy, and only time will tell whether it performs better. But I am happy already with the performance of the filter.UPDATE - 08/24/2011 - After a couple of gas fill ups, I can tell you that the filter definitely has improved my gas mileage. Before the air filter I was getting 21 or 22 MPG. Now I get between 23 and 24. Is it a big deal? Maybe not, but over time I will save some money and it does confirm that the air filter does work better than the typical filter. One other thing I have noticed is that the engine seems a little louder than before.
