This 2010 Audi S4 is equipped with a shorth shifter kit by Hypershift. This addition gives the driver more control of his/her shifting, and also gives you a 45% reduction in throw while shifting. Next we added a APR 3.0 TFSI Supercharger Pulley Upgrade. Once we got done with the pulley upgrade, we added a RCS S4 Catback Exhaust from APR to add to the performance of the car as well as the sound. Lastly we installed a Carbonio Air Intake System. This is a very neat intake system as the Carbono intake system simplifies the intake system by directing all incoming air directly at the filter. This allows for faster throttle response and increased torque at all RPM's.
