Great replacement for my Jeep. Already notice the increased gas mileage and performance.

I ordered the air filter for our 2012 Jeep Liberty. It arrived very quickly. I have used a K&N filter on my 1994 Wrangler and was very happy with it. I will be ordering one for my 2009 Jeep Wrangler 2dr next.

Filter is as advertised. Cannot tell if getting better mileage since it is winter in Idaho.

2011 Jeep Liberty Renegade 3.7L, 4x4, trail rated has a real world city driving increase of about 1.6 mpg on the uphill / downhill area driven. Haven't taken it out on the freeway for a long trip yet but if the city driving is any indication, I would expect highway mpg to possibly increase by about 3+ mpg. Jeep KKs & JKs do not get good mileage because of the non-aerodynamic (flat) front end, low gearing and extra weight from under chassis skid plates so this is a pleasant surprise. Low end acceleration has a felt increase, especially from a standing start on a 5% or more uphill grade, without sacrificing the increased mileage. Because of the increased engine performance, the transmission shifts faster into the next higher gear and holds the gear longer under load. I would buy another K&N air filter for any vehicle I own.
