Spool Performance S63 AMG [M177] Spool FX-170 Upgraded High Pressure Pump Kit

The Spool Performance FX-170 High-Pressure Fuel Pump Kit is engineered to enhance the fueling capabilities of your Mercedes-AMG S63 [M177]. Offering a significant upgrade over stock, the FX-170 features a larger bore size that delivers approximately 50% more fuel flow, making it an excellent choice for high-performance tuning and handling higher ethanol concentrations.

Key Features of the FX-170:

• 50% Increased Flow: Upgraded bore size provides 50% more fuel flow compared to the stock pump, supporting higher ethanol blends and bigger turbo setups.
• E85 Compatible: Fully compatible with ethanol fuel mixes, ensuring reliability and performance under demanding conditions.
• Plug and Play Installation: No cutting or splicing required, allowing for a straightforward and hassle-free installation.
• Higher Pressure Capability: Supports increased pressure levels to meet the demands of high-performance applications.

Why You Need the FX-170:

The stock high-pressure fuel pump (HPFP) on the M177 engine is limited in its capacity to support increased power and tuning. The FX-170 pump enhances fuel flow by 50%, addressing these limitations and allowing for the use of larger turbos and higher ethanol concentrations. This upgrade is crucial for maximizing engine performance and efficiency.

What’s Included:

• 2x FX-170 upgraded high-pressure fuel pumps
• 1x Ethanol Content Monitor (optional) with mobile apps
• 1x Bosch spec 10-micron high-flow fuel filter
• Upgraded fuel lines and installation hardware

Spool 10-Micron Filter Unit:

The included 10-micron filter unit provides superior filtration without significant pressure loss in the low-pressure fuel system. This filter unit helps protect the high-pressure pump and injectors from debris, ensuring optimal performance and longevity.

Spool Ethanol Content Monitor:

The Spool Ethanol Content Analyzer (ECA) kit offers digital readouts of in-tank ethanol content and fuel temperature via BLE 4.0 low-energy technology. This setup allows for simultaneous Bluetooth connectivity with other devices. The ECA module includes a 0-5V filtered output for flex-fuel integration if needed. Fuel lines in the kit are braided steel with a nylon core, 100% E85 compatible.

Tuning Requirements:

The FX-170 pumps require calibration changes to function correctly. It’s essential to apply these changes before starting the vehicle to avoid damage and warranty issues. Spool Performance can provide calibration details and assist in connecting with experienced tuners for optimal results. Custom tuning is necessary to achieve maximum performance with the upgraded pump setup.

Low-Pressure Fuel Pump Upgrade:

Proper low-pressure fueling is critical for the high-pressure pumps and injectors in a direct-injection (DI) system. Inadequate low-pressure fueling can lead to damage and voided warranties. It is essential to plan your fuel system build with appropriate low-pressure upgrades to ensure reliable operation and avoid potential issues.
