Installation was very easy. The engine has more very noticeable horsepower you can feel in the pedal when the time calls for it. Gas mileage has improved greatly. All in all a great buy for anyone that loves their Ford Ranger as much as I do. Now if everyone will excuse me I want to go trade some gas for horsepower in my awesome truck thanks to K&N.
Very pleased with the Airaid system. It is designed well and was easy to install. I like the design of the unit and the instructions were well written. Throttle response is improved and initial results indicate improved mpg. My truck seems to cruise at highway speeds requiring less throttle than before.
