Spool Performance S63 AMG [M177] Spool FX-200 Upgraded High Pressure Pump Kit

The Spool Performance FX-200 High-Pressure Fuel Pump Kit is an essential upgrade for the Mercedes-AMG S63 [M177], designed to support high-performance tuning and power enhancements. Featuring a larger bore size, this pump provides an 80% increase in fuel flow over the stock pump, making it ideal for higher ethanol concentrations and bigger turbo setups. Fully E85 compatible, this plug-and-play solution requires no cutting or splicing, ensuring a seamless installation and improved performance.

Key Features of the FX-200:

• 80% Increased Flow: Larger bore design increases fuel flow to accommodate higher ethanol blends and larger turbos.
• E85 Compatible: Fully capable of handling ethanol fuel mixes, offering greater flexibility for performance builds.
• Up to 240 Bar Pressure: The FX-200 delivers higher-than-stock pressures, increasing fuel injector output and reducing injection times.
• Plug and Play Installation: No cutting or splicing required; direct replacement for stock components.
• Superior Filtration: Equipped with a Bosch-spec 10-micron high-flow fuel filter, ensuring top-level filtration without pressure loss.

Why You Need the FX-200:

The stock high-pressure fuel pump (HPFP) in the M177 engine is insufficient when tuning for higher horsepower and torque. The FX-200 pump adds 80% more flow, significantly raising the fueling limits, allowing for the use of larger turbos and higher ethanol blends. This upgrade is crucial for those pushing their AMG to new performance levels while maintaining fuel supply stability and engine safety.

What’s Included:

• 2x FX-200 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 is designed to offer the best filtration available on the Mercedes market, keeping the high-pressure pump and injectors safe from debris while maintaining optimal pressure in the low-pressure fuel system.

Spool Ethanol Content Monitor:

The kit includes an optional Ethanol Content Monitor, providing digital readouts of in-tank ethanol content and fuel temperature. Using BLE 4.0 low-energy technology, it allows simultaneous Bluetooth connectivity with other devices. Fuel lines in the kit are braided steel with a nylon core, 100% E85 compatible.

Tuning Requirements:

Upgraded pumps require calibration changes. It’s essential to apply these changes before starting the vehicle to prevent damage and maintain warranty coverage. Spool Performance provides calibration details and can connect you with experienced tuners for optimal tuning.

Low-Pressure Fuel Pump Upgrade:

Proper low-pressure fueling is critical to ensuring the high-pressure pumps and injectors function correctly. Inadequate low-pressure fueling can cause damage to the pump pistons and bores. A low-pressure fuel pump upgrade is highly recommended to avoid any potential issues and ensure your high-pressure system operates efficiently.
