My idea i had while listening to my proffesor ramble on in class was to use a intercooler i had seen for the 240sx on my pulling truck, as a slim price alternative to a $1500 spearco intercooler. The intercooler i found is made by cx racing and is bar plate design and at 270 bucks new its sounds like a real good deal. My question is how well will this work or will it be any better than my leaky stock one. The specs:

Intercooler Core Size 24"x11"x3", Overall Size 31"x11"x3", 2.75" Inlet & Outlet, 3" Thick Core.

on a stock Cummins, 30"x11.5"x1.5 " long and poor extruded tube design.

why not get a replacement stock intercooler?

stock intercooler is 2x the size of that intercooler you posted...

 

i believe this will do the job
