I have one and the install wasn't too bad. Just needed some force for the grooves to line up on the intake box. Additionally, you may want to put some silicon sealer (I used hightemp black from permatex because I had that lying around) to seal the silver knob where the plastic hose connects on the elbow. It was a little loose on mine and I didn't want a gap or leaks. Other than take study the video and you're good.
BTW should this be in the engine section?
