The HKS 11004-AH006 is a GT4845 Sports Turbine Kit designed for the Honda Civic Type R FK8 and FL5 equipped with the K20C engine. This kit replaces the factory turbocharger with an HKS GT4845 unit enabling significant power gains at high RPM, not achievable with the stock turbo. The Direct Fit design uses the same location and bracket configuration as the factory turbo for a bolt-on installation without modification. The kit includes all necessary gaskets (turbo, exhaust, intake, water and oil lines) and replacement hardware. Tested at Fuji Speedway: +12 km/h top speed gain and 3 seconds faster lap time. Maximum power with HKS Mastery ECU Phase 3 JDM: 282 kW (384 hp) at 6,600 rpm. No fuel system upgrade required thanks to optimal size design.
