Cool, are those brackets hard to make, i think i seen a thread here before about installing itr boxes, must go find it.
I read somewhere these are a good upgrade for an ek9?
See here my DIY when i put an ITR airbox into my EK4:

I just read and bookmarked that haha nice write up.
Did you find any differance in performance?
Oh and do you need the dc2 piping or does the ctr piping fit?
