Spool Performance GLC63 AMG [M177] Spool FX-170 Upgraded High Pressure Pump Kit

Upgrade your GLC63 AMG’s fueling system with the Spool Performance FX-170 High Pressure Pump Kit. This performance-enhancing kit is designed for the 4.0L V8 bi-turbo engines, providing an essential boost in fuel flow and pressure to support higher ethanol concentrations and larger turbo setups.

What is the FX-170?

The FX-170 is a high-pressure fuel pump that offers approximately 50% more flow compared to the stock pump, thanks to its larger bore size. It is fully E85 compatible and features a plug-and-play design, requiring no cutting or splicing during installation. The increased flow capacity allows for higher ethanol blends and provides the necessary fueling for larger turbos, enhancing overall engine performance.

Why Do You Need It?

The stock high-pressure fuel pump (HPFP) on the M177 engines limits tuning potential and output increases. The FX-170 addresses this by adding 50% more flow, raising the fueling limits and supporting more aggressive tuning, including the use of larger turbos and higher ethanol concentrations.

What Does the Kit Include?

• 2 x FX-170 Upgraded High-Pressure Fuel Pumps: Boosts fuel flow and pressure to meet performance needs.
• 1 x Ethanol Content Monitor: (if selected) Features a mobile app for real-time ethanol content and fuel temperature readings.
• 1 x Bosch Spec 10-Micron High Flow Fuel Filter: Ensures superior filtration with minimal pressure drop.
• Upgraded Fuel Lines and All Necessary Install Hardware: For a complete and straightforward installation.

Spool 10-Micron Filter Unit

The 10-micron filter unit provides top-tier filtration without causing significant pressure drops. It protects the high-pressure pump and injectors from debris, ensuring reliable operation and performance.

Spool Ethanol Content Monitor

The Spool ECA kit includes a digital readout for in-tank ethanol content and fuel temperature, delivered via Bluetooth 4.0 low energy technology. The ECA module also features a 0-5V filtered output for potential flex-fuel implementation. The included app allows for convenient monitoring and adjustments.

Are Tune Changes Required?

Yes, calibration changes are required for the upgraded pumps. Apply these changes before starting the vehicle to prevent damage and avoid warranty issues. Spool Performance can provide calibration details to your existing tuner or help connect you with experienced tuners. Custom tuning is necessary to optimize the pump setup for your specific vehicle and conditions.

Low Pressure Fuel Pump Upgrade

Adequate low-pressure fueling is crucial for the proper function and durability of high-pressure pumps and injectors in a direct-injection system. Insufficient low-pressure fueling can lead to damage and void warranties. Plan your fuel system build with appropriate low-pressure upgrades to prevent such issues.
