KraftWerks 12 Civic Si Supercharger Kit (Only Comes w/120mm Pulley - Must Order 110mm Separately)

The Kraftwerks intercooled supercharger system for the 2012-2015 Honda Civic Si (2.4L) features a Rotrex C30-94 head-unit, delivering a linear power curve, on-demand torque, and cooler operating temperatures. Its patented traction drive technology provides instant throttle response and a progressive power increase up to redline, avoiding the "spiking" or "surging" of turbochargers. Rotrex superchargers are compact, efficient, and operate quietly with low vibration. They utilize a self-contained oiling system independent of the engine, with a dual-action oil pump and fluid cooler. This kit includes all necessary brackets and hardware for a bolt-on installation without cutting, drilling, or welding.
