Any improvement on cooling efficiency? Looking to install that on my STI to improve the cooling system, right now I have installed the Koyo radiator and Cosworth thermostat but if that will help to improve the water flow that be awesome. Supposedly according to Killer B site it will reduce the cavitation flow.
