I think I should learn this valuable tip each time I try to install something, but I never stick to it..
"to save many hours from trips to the store, make sure you got the RIGHT tools before you start"
otherwise this kind of stuff happens.. lol
So, to save you guys time if you don't have tools accessible already, this requires a few hand tools:
-screwdriver/pliers (to remove the plastic lock nut holding the plastic molding)
-17mm socket (for the spoon assembly nuts)
-10mm socket (for the top plate bolts)
-14mm deep socket (for the engine mount nut)
- 10" socket extender
- hex wrench #6
-torque wrench (40lbs for the engine nut; 25lbs for the spoon nuts; 10-20lbs for the top plate assembly)
Here is the instructions that made no sense except for the pictures.. but with this great forum and its members, everything was cleared up! Thanks Fitinfit and Ben!
1) this requires the plastic lock nut to be removed to lift the plastic molding upwards for the top plate to be installed. This plastic molding can be trimmed to have a 'cleaner' appearance, this will require extra tools.
The windshield hose will need to be unbolted as well, the other two mounting bolt holes are covered by two black stickers seen in the photo.

tools used:
2)before I install the top plate, I took the advice of
fitinfit 
and turned the wheel this way to get better reach under the car. it really helped!
3) Looking under the car, the bolts can easily be spotted. the hard part was getting the nut up there without dropping it. Once the nut is screwed on, tighten the bolts to 10-20lbs of torque. (I just tightened as tight as I could because I got the torque wrench after this step)
Top plate installed!! Easy
Not sure if this is a concern, but the top plate seems like it is touching the pipe in the picture. I am thinking the damper is going to move back and forth, but then the steel plate shouldn't be moving which means it wont be moving the pipe too right? I'll periodically check to make sure there isn't any rubbing going on.
4) Installing the lower piece was tricky at first, but it was easier than I expected. The engine mount nut is going to be taken off. No engine support is needed. Here are the tools I used: (make sure you aren't using any small socket adapters like I did or else the first picture posted will occur

)
Once you have the nut removed put the plate on like so..

You can notice the nut is not fully screwed on. I am not sure if this will be a problem, but it did feel pretty secure once I tightened to 40lbs of torque with my new trusty torque wrench.
The most concerning part was probably the lower piece. But it isn't hard at all (a monkey could do it according to some people

).
5) Spoon damper installation. Pretty much bolt on. Unscrew the top piece to lengthen the damper rod to match the two steel plates, then screw on the allen bolts. There is a 17mm lock nut on the lengthening rod that is supposed to be tightened to 25lbs of torque i believe.
6) there is two spoon stickers included, I believe to stick on the damper. I did put on on, but didn't take a picture, maybe I'll take a picture later of the whole engine bay to show matching blue intake and damper

but for now, I will test and report any differences I feel. Hopefully there is a positive difference, so I know I installed it correctly
Quick review: it really dampens!

The difference is definitely noticeable!
-There is less jerking during shifts when accelerating fast. Especially when shifting at high revs.
-Downshifting has less jerking as well. I tried to downshift at the earliest point to see max jerkiness, the ETD does reduce it significantly!
-no vibrations noticed or increased noise yet.
One potential issue is the lower plate installation.
Fitinfit said I am missing a bolt where the screwdriver points to. PMed Ben about it, hopefully he has the answer.
The bolt seems long enough for just the original mounting plate and the nut to be fully screwed on. The nut was able to screw on about 85-90%. you can compare the two before and after photos above.
