Fantastic directions!

"After the box was out I removed the elbow from the air intake duct and is small."

Since a picture is worth a thousand words...

"After getting that corner loose and fumbling with the rest for a few minutes trying to take it out gently (The plastic is very brittle so no matter how you handle the entrails of the box, the plastic will snap or crack and quite possibly pinch or cut you)"

Its possible to remove the frame without cracking it. On the opposite side of the box away from the inlet are two plastic 'fangs' that hold that side of the frame in place. You need to disconnect that side first. If you put a screwdriver between the fangs you can usually pry the frame over them without breaking it. Then just unclip the other side and the whole thing lifts out. Since you don't use the frame anyway it doesn't really matter which way you remove it. Took me several attempts before I got that frame out without breaking it.

BTW, when cleaning the box I scrub them down. Beware of those fangs... they can bite!

"once the cut is through, you will encounter resistance on the inside of the box and the saw may seize. "

If it seizes depending upon how you are holding it and the box can hurt. I use a 4" hole saw as well but have a jig for the insides of the box to give me a pilot hole to keep the saw from wandering. I've found cutting the hole while exerting no pressure on the saw (just enough to keep it touching the plastic) works best and keeps it from binding. Takes an extra minute or two but you won't hurt yourself.

"There now is torque where there was none before and you can feel it."

Yup. It really changes the character of the engine.
