    Will i have to buy a new cai or will my k n still work with super charger. I'm looking for supercharger that u can hear it wine under acceleration is this it? And do they sell other pullys that would help create more boost?

    • The Whipple W140AX 2.3L Intercooled Supercharger Kit will include its own cold air intake and would be incompatible with cold air intakes meant for the stock throttle body location. This supercharger will produce a distinct wine on hard acceleration, and additional pulleys are available through Whipple directly, however increases to boost may require additional modifications.
