Part fit well went on easy. Definent seat of pants horsepower increase. Sounds great under throttle no different at idle.

Very well made. High quality. Installation was straight forward and simple. Most noticeable difference after install was throttle response and huge sound difference. Now my 5.3L has a mean growl to it when i accelerate. Too early to criticize fuel economy. Over all it looks great, sounds awesome and i am very pleased. Highly recommend this instake system.
