KraftWerks is proud to introduce its Rotrex-based supercharger system for Honda’s ’06-’11 Civic Si. Based off of the Rotrex C30-94 supercharger, the KraftWerks Civic Si kit produces impressive results throughout the entire powerband—unlike any forced induction system you’ve experienced. Rotrex’s patented traction drive technology means that power’s always available. Like all KraftWerks Supercharger kits, Civic Si systems include all necessary brackets, electronics, and hardware for a true bolt-on installation.
