Spool FX-170 HPFP Kit | AMG M276
The Spool Performance FX-170 is a high-pressure fuel pump (HPFP) upgrade for Mercedes-Benz M276 engines. This solution is designed to remove the limitations of the standard fuel system, enabling higher power outputs and ethanol blends in tuned applications.
What is the FX-170?
The FX-170 is an upgraded HPFP with a larger piston diameter than the standard pump. This enables approximately +50% greater fuel flow.
- Approx. +50% flow compared to stock
- Full E85 compatibility
- Plug & Play installation without modifications
- Allows for greater fuel delivery
Additional capacity enables:
- Higher ethanol blends
- Larger turbochargers
- Wider tuning possibilities
Why is an upgrade necessary?
The M276 engine's stock HPFP is a significant limitation in tuning:
- Fuel delivery is insufficient for high power levels
- The use of ethanol blends remains limited
The FX-170:
- Significantly increases fuel system capacity
- Expands the platform's fuel limits
- Enables more effective and safer tuning

Important Note: LPFP
The low-pressure fuel system is critical:
- Insufficient supply can damage the pump and injectors
- HPFP lubrication relies on fuel flow
- Lack of fuel can lead to wear and failure
Recommendation: ensure adequate low-pressure side upgrade
