For packaging and efficiency, air/water is the only option for a positive displacement supercharger system. Chevrolet, Cadillac, Ford, Bugatti, Audi and Mercedes Benz all seem to concur. Another advantage is that with our super efficient Laminova cores, under-stressed OEM grade BOSCH pump and simple hose routing, one can quite easily mount a larger core heat exchanger without having to reengineer complicated and expensively fabricated air/air intercooler piping. With that said, we believe users will be quite content with the intercooled kit's supplied large surface area heat exchanger.
