Spool 10-Micron Filter Unit:

This high-performance inline filter offers the best protection available for M177 applications without restricting fuel flow. Built to Bosch specifications, it keeps your HPFP and injectors free from contaminants while supporting high volume and ethanol-based fuel types.

Spool Ethanol Content Monitor:

The ECA (Ethanol Content Analyzer) system provides Bluetooth 4.0 digital readouts of both ethanol content and fuel temperature directly on your smartphone or smartwatch. It also includes a 0-5V analog output for flex-fuel ECU integration if needed.

Tuning Requirements:

Custom ECU calibration is required. Do not start the vehicle without updating the tune to accommodate the FX-170 system. Spool Performance provides data to your existing tuner and can connect you with experienced professionals for optimal results.

Low Pressure Fueling Advisory:

To avoid premature wear or damage to the FX-170 pumps, ensure that your low-pressure fuel pump system is upgraded accordingly. The HPFPs rely on consistent low-pressure fuel feed for proper lubrication and operation. Inadequate supply will void the warranty due to detectable wear from starvation.

Unlock the full potential of your AMG GT63’s M177 engine with the Spool Performance FX-170 HPFP system—engineered for high output, E85 versatility, and long-term reliability.
