Mercedes-AMG GT63 Spool FX-200 High Pressure Fuel Pump Kit
The Spool FX-200 high pressure fuel pump kit for the Mercedes-AMG GT63 adds roughly 80% more flow than the stock pump, so the M177 can support bigger turbos and higher ethanol blends.
Why you need it
The stock high pressure fuel pump on the M177 is the first fueling limit you hit when tuning. The FX-200 uses a bigger bore than stock for roughly 80% more flow, can run pressures up to 240 bar for more injector output, and is fully E85 compatible.
