Spool Performance Spool FX-170 Upgraded High Pressure Pump Kit [N63] - SP-FX-N63

The Spool Performance FX-170 High-Pressure Fuel Pump Kit is a high-performance upgrade for BMW N63 engines, providing an essential solution for enthusiasts looking to push the limits of their vehicles. This pump features a significantly larger bore size, delivering roughly 50% more fuel flow compared to stock pumps, making it perfect for high ethanol blends and larger turbo setups. The FX-170 is 100% E85 compatible, fully plug-and-play, and operates at 25% higher pressure than the OEM HPFP, giving injectors the ability to flow more fuel for improved performance.

Key Features:

• 50% Increased Fuel Flow: The larger bore design provides up to 50% more flow compared to stock, allowing higher ethanol concentrations and support for larger turbos.
• E85 Compatibility: Fully compatible with ethanol blends, making it ideal for performance tuning.
• Higher Operating Pressure: Capable of running at 25% higher pressure than stock pumps, ensuring injectors can deliver more fuel with the same opening time.
• Plug-and-Play Installation: No cutting or splicing required, making installation straightforward.

Why You Need It: The factory HPFP on the N63 engine is often a limiting factor when tuning for higher output. The FX-170 significantly improves fuel flow and injector performance, raising the platform's fueling capacity to support more aggressive setups like bigger turbos and high ethanol blends.

Kit Includes:

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

Additional Components:

• 10-Micron Filter Unit: Offers superior filtration without pressure drops, protecting the high-pressure pump and injectors from debris.
• Ethanol Content Monitor: Provides real-time monitoring of ethanol content and fuel temperature via a mobile app using BLE 4.0 technology. The app is designed for ease of use with both regular Bluetooth and the Spool ECA module.

Tune Changes Required: To achieve optimal performance, tuning adjustments are necessary before running the FX-170 kit. Spool Performance provides calibration data for your tuner or can assist with connecting you to experienced tuners. Proper tuning ensures maximum power gains while preventing potential damage.

Low-Pressure Fuel Pump Consideration: Upgrading your low-pressure fuel system is crucial for the durability of the high-pressure pump. Inadequate low-pressure fueling can lead to damage in the HPFP, voiding the warranty. Ensure your fuel system is properly planned with low-pressure upgrades as needed.
