M&M Honda CIVIC FL5 big turbocharger KIT

Replace the air cleaner with a new one. This will be a genuine turbine replacement. Since it is a big turbine, it is necessary to simultaneously install the fuel system upgrade kit and set it with HONDATA FlashPro. It is also recommended to install a reinforced twin clutch set.

This is a large capacity turbocharger KIT. Using a big turbine manufactured by the reliable Mitsubishi Heavy Industries Engine & Turbocharger (MHI), we have maximized the power output and torque in the high rotation range without sacrificing low and medium speeds. Installation can be done with the same bolt-on method as the original. Optimization and increased capacity of the compressor wheel and turbine blades contribute to improved accelerator response.
