Just installing the XS intercooler which I bought used but is a Jfizzle kit. One quick question is that it came with 2 different sized brass fittings and no instructions.

I assume that everyone is reusing the stock water hoses, in that I used the long hose to go from the rear of the IC to the exhaust and the old exhaust hose as the new inlet for the IC.

Now I currently have it setup so that the larger diameter hose in on the rear and the smaller diameter hose is on the front.

My guess was the smaller fitting will pressureize the cooler a little more and create more of a spray into it making cooler air?
