The K&N 63 Series AirCharger High-Flow Intake Kit was easy to install but did require a bit of time and patience. Overall, it took about an hour. There is a significant increase in under the hood noise. The technical info says that installation will increase horsepower and gas mileage. Well, a seat of the pants review of HP indicates a slight change. Gas mileage hasn't been better because I can't keep my foot off the gas!
