Completed the installation of the alt intake air this morning. It's pretty straightforward. Just follow the instructions. There are a couple of noteworthy things though;

This is intended to be emergency use only and is not typically pilot resettable without pulling off the top cowl. Picture 3 shows why; I suppose there might be a cable routing where this would work, but in my case, what happens is that theres enough slop in the cable that if you try to push it back closed it doesn't quite rotate all the way and the the locking tab at the top doesn't nest properly.

Also, the plans call for a -12 adel clamp around the cylinder #2 oil return line B nut as a mounting point for the cable housing. It worked much better to go with a smaller clamp on the line right below the B nut, but I suspect that this would depend on the exact location you installed the door and the pivot point.
