Mine is in place, fitted it a long time ago, I had it on my last Legnum, and transferred it over to my new one, it went in there fine. I used a standard Legnum bottle with two pumps.
I had to fit a low water level unit to it, (wired to an led in dash)
Intercooler spray, I got atomising jets so it creates a fine mist infront of the intercooler.
My WI pump is fitted right beside the bottle so very short distances between bottle and pump and nozzle in post cooler intake pipe.
Intercooler spray is activated automatically when meth injection starts, (or can be switched separately)
