Supercharger Kit

The KraftWerks Supercharger Kit provides a significant performance upgrade for the 2006-2011 Honda Civic Si, specifically models equipped with the K20Z3 engine. This comprehensive kit includes the Rotrex C30-94 supercharger, known for its self-contained oiling system, along with a high-flow intake manifold and a front-mount intercooler to optimize air intake and cooling. All necessary piping, brackets, and hardware are provided for a complete bolt-on installation. Installation can typically be completed over a weekend with basic hand tools and access to a lift. The system delivers up to 380 horsepower and 240 lb-ft of torque, characterized by a smooth, linear power curve with instant throttle response and reduced detonation risk due to lower intake temperatures. Crucially, this supercharger kit requires tuning. It does not include a tuning device; therefore, a Hondata FlashPro is mandatory for remapping the engine's parameters after installation. KraftWerks offers a downloadable base tune for FlashPro users, but a professional custom tune is strongly recommended to optimize performance and ensure engine safety. Operating the vehicle without proper tuning after installation can lead to engine damage. Additionally, an upgraded clutch is highly recommended to effectively handle the increased horsepower and torque output.
