Be the first to review part E-1447
My Jeep was sluggish on my commute and only got about 16.5mpg in mixed driving, so I was really interested in the K&N Intake Kit for my 2008 Liberty. The install took about two hours, mainly because it was very difficult to make out details in the example photos, and I had to build everything first before tightening all the fittings to ensure it would all sit and fit correctly under my hood. Once it was in place I took a quick test drive. AMAZING I now have so much power coming out of that little 3.6L engine, but I haven't put it on a dyno. Even my wife is impressed with the pick up that intake and filter provide. Now, my mileage has dropped a bit to 15.9 in mixed driving, but since it can now pass like my Oldsmobile Intrigue could, I'm probably driving much more aggressively than I realize.

Now getting better than the 2015 Buick Encore AWD SUV/MPG 23 city / 30 highway with my K&N air filter MPG: 27 city / 32 highway . Buying the next 180 gallons of gas will pay for the cost of my filter.

Hard to prove but haven driven the Buick for nine years I feel that acceleration is better, not much but better and highway response as well.
