Spool FX-170 upgraded high pressure pump kit [M276]

Spool Performance FX-170 High-Pressure Fuel Pump Upgrade

What is the FX-170?

The FX-170 is a high-performance upgrade to your stock high-pressure fuel pump, featuring a larger bore size that delivers approximately 50% more flow compared to the factory pump. Fully E85 compatible and plug-and-play, this pump requires no cutting or splicing, making installation seamless. With the added flow capacity, you can run higher ethanol blends and support the fueling needs of larger turbos.

Why Do You Need It?

The factory high-pressure fuel pump (HPFP) on the M276 engine quickly becomes a limiting factor when tuning for more power. The FX-170 solves this by increasing fueling capacity by 50%, enabling you to support bigger turbos, higher boost levels, and ethanol blends without running into fueling constraints.

What’s Included in the Kit?

• 1 x FX-170 High-Pressure Fuel Pump
• 1 x Bosch-Spec 10-Micron High-Flow Fuel Filter
• Upgraded Fuel Lines and All Necessary Installation Hardware
• Optional: Ethanol Content Monitor Kit with mobile app for real-time ethanol content and fuel temperature monitoring

Spool 10-Micron Filter Unit

This 10-micron filter provides the highest level of filtration available for the M276 platform while maintaining excellent flow. It protects your HPFP and injectors from debris, ensuring durability and long-term reliability. Highly recommended for any build.

Spool Ethanol Content Monitor

The Spool Ethanol Content Analyzer (ECA) gives you real-time ethanol content and fuel temperature readings via Bluetooth (BLE 4.0). Compatible with our free mobile app, the kit includes braided steel nylon-core fuel lines that are 100% E85 compatible, offering both performance and reliability.

Are Tune Changes Required?

Yes, calibration adjustments are required with the FX-170. These changes must be made before starting the engine to avoid damage and maintain the product warranty.

• Spool Performance provides calibration data to your tuner or can connect you with experienced tuners who specialize in our pumps.
• While Spool Performance doesn’t provide custom tuning services, we are available to assist with any questions your tuner may have.

Low-Pressure Fuel Pump Upgrade

A properly designed low-pressure fuel system is essential for the durability and performance of high-pressure pumps and injectors in direct-injection setups. Inadequate low-pressure fueling can cause damage to the pump piston and bore, which are lubricated by fuel. This damage is detectable and will void warranties. Plan your fuel system upgrades carefully to ensure proper low-pressure support for your high-performance setup.

The FX-170 is the ultimate solution for unleashing the full potential of your M276 engine, ensuring your fuel system can handle whatever your build demands.
