I am going to start offering Intercoolers on Amazon. I have decided this. Nice Shiny Intercoolers, in the size and shape that fit my car. This is the first one. An Intercooler cools the pressurized air that is passing through your forced induction device. This could be a supercharger or a turbocharger it doesn't matter, the thing is that you want one made of a good conductor of heat. Aluminum is an excellent choice. Silver would be better, Gold would be best. I can't afford a solid gold intercooler, and if I could I wouldn't put it on my car for fear it would be stolen, so I chose aluminum.
