Spool FX-170 Upgraded High Pressure Pump Kit [M157]

Introducing the Spool FX-170 Upgraded High Pressure Fuel Pump Kit, designed specifically for the Mercedes M157 platform. After nearly a year of rigorous testing, this fuel pump upgrade offers a groundbreaking solution for enthusiasts looking to break the limitations of the stock high-pressure fuel pump.

The FX-170 pump features an enlarged bore size that delivers approximately 50% more fuel flow than the OEM pump, making it perfect for high-performance applications such as bigger turbos and running higher ethanol concentrations. Its plug-and-play design ensures easy installation without the need for any cutting or splicing, providing both simplicity and reliability.

Why You Need the FX-170

The stock high-pressure fuel pump (HPFP) on the M157 engine has limited capacity when tuning for higher power. The FX-170 resolves this issue by significantly increasing fuel flow, allowing for higher power outputs and better ethanol blend compatibility. With the FX-170, you'll unlock the potential of your vehicle, supporting bigger turbos and aggressive tunes with higher ethanol concentrations.

Kit Includes:

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

Spool 10-Micron Filter Unit

This high-performance inline filter ensures superior filtration without causing any noticeable pressure drop. It protects the high-pressure fuel pump and injectors from debris, making it an essential component for maintaining the longevity and efficiency of your fuel system.

Spool Ethanol Content Monitor

The included Spool Ethanol Content Analyzer (ECA) provides real-time digital readouts of ethanol content and fuel temperature via Bluetooth 4.0. The app also features an ethanol mix calculator, allowing you to perfectly blend your fuel every time.

Tuning Requirements

Installing the FX-170 requires tuning adjustments to maximize its potential. These changes must be applied before starting the vehicle to prevent damage and voiding the warranty. Spool Performance provides calibration details to your tuner and can connect you with experienced tuners familiar with the FX-170 pump system.

Low Pressure Fuel Pump Upgrade

For optimal performance, it's crucial to ensure that your low-pressure fuel system is upgraded to match the demands of the high-pressure pumps. Inadequate low-pressure fueling can cause significant damage, so proper planning is necessary when upgrading your entire fuel system.
