i finally got around to milling out the water heated box for my old style clifford intake. i cut it down to the same size as the flat place on the bottom of the intake about 4.500 x 4.800 and it is 2.500 deep. i left the sides the same thickness as the intake and the bottom about .500 . i tried to make one like the pictures i saw from twisted6. where do i bring in the water from and return it to? i guess i will use heater hose but i have to know what size of barbs to buy and what size of threads to cut in front and back, so first i need to know how to run the hose. thanks, hoggyrubber
