tonneau cover& cold air-intake?

hello everyone, new to the forums, just order the Extang Trifecta Folding Tonneau Cover, and the K&N 63 Series AirCharger High-Flow Intake Kit,will be in this weeked. wonder if anyone in here had install these items, how hard or easy it this to install, and how well does it work..any infor would be a great help

 

everything your looking to add are easy installs.most people on here are against the k&n.for the money afe seems to be the best priced.i myself just run a drop in and removed the secondary airfilter.you most likely will not get a hp gain,throttle response and seat of they pants feel is all i have noticed allong with most others on here.welcome to tw there is some good info on here.
