This high-performance pump operates at 25% higher pressure than the stock unit, allowing injectors to flow more fuel per cycle for improved power and efficiency.

The FX-170 is fully E85 compatible and features a plug-and-play design, which requires no cutting or splicing during installation. It’s engineered to offer significant improvements in fueling capacity, stability, and reliability, making it perfect for those pushing the limits of their BMW M5, M6, or other high-performance S63-powered models.

Why You Need It:

The Gen 1 S63 HPFP is a known bottleneck when pushing the engine to higher horsepower levels, especially when tuning with ethanol blends or larger turbo setups. The FX-170 resolves this limitation by:

• Increasing fuel flow by 50%, enabling support for higher ethanol blends and big turbo applications.

• Boosting injector output, extending the fueling capacity of the platform to accommodate larger power goals.

• Improving fuel delivery stability, ensuring consistent performance under high-boost, high-power conditions.

Whether you're running a F10 M5, F12/F13 M6, or X5M/X6M, the FX-170 is a crucial upgrade to unlock the full potential of your S63 engine.

What’s Included in the Kit?

• 2x FX-170 Upgraded High-Pressure Fuel Pumps

• 1x Optional Ethanol Content Monitor Kit with mobile app support

• 1x Bosch-Spec 10-Micron High-Flow Fuel Filter

• Upgraded Fuel Lines & Complete Installation Hardware

• Spool 10-Micron Fuel Filter

High-Performance 10-Micron Fuel Filter:

Included in the kit is a Bosch-Spec 10-Micron High-Flow Fuel Filter, which offers the best filtration for the Gen 1 S63 platform. This filter ensures optimal fuel flow with zero pressure drop, protecting your HPFPs and injectors from harmful debris. This protection contributes to long-term reliability and performance.

Spool Ethanol Content Monitor:

For those running ethanol mixtures, the Spool Ethanol Content Analyzer (ECA) Kit is a valuable addition. It provides real-time ethanol content and fuel temperature readings via the Spool Performance mobile app. Using Bluetooth Low Energy (BLE 4.0), the system ensures smooth, uninterrupted data transmission while maintaining compatibility with other Bluetooth devices. The kit also features durable, 100% E85 compatible braided steel nylon-core fuel lines for maximum durability.

Are Tune Changes Required?

Yes, custom tuning is necessary when upgrading to the FX-170 HPFP. Calibration changes are required before starting the vehicle, and Spool Performance provides necessary calibration details to your tuner. Although Spool does not offer custom tuning services, we offer support to help you connect with experienced tuners to ensure optimal fuel delivery for your modifications and ambient conditions.

Low-Pressure Fuel Pump (LPFP) Upgrade:

To ensure the longevity and performance of the upgraded high-pressure fuel pumps and injectors, a properly upgraded low-pressure fuel system is essential. Insufficient LPFP supply can cause premature wear or failure of the HPFP due to inadequate fuel lubrication, which can damage components and void warranty coverage. It's crucial to upgrade the LPFP to match the increased fueling demands of high-power applications.
