This was simple to install- I'm no mechanic and it took 1/2 hour. Replaces the factory airbox and the corrugated tube, hooks up to the factory (resonator?) not all the way over to the throttle body. You can hear the difference and feel some at higher RPM. I installed with a Bully Dog GT, drove 250 miles on I-80. Slowing to idle it does vibrate, but I've had 2 Frontiers and my Dad has one, they all seem to rattle like a diesel at low RPM. Maybe a bit of mileage increase (1-2 mpg).
