Spool FX-200 BMW N55 Upgraded High Pressure Fuel Pump

The Spool FX-200 High-Pressure Fuel Pump is an advanced upgrade designed specifically for BMW N55 engines. As a successor to the FX-180, the FX-200 delivers roughly double the fuel flow of the stock pump, offering significantly improved fueling capabilities. It’s fully E85 compatible and features a plug-and-play installation, meaning no cutting or splicing is required. The increased flow allows for higher ethanol concentrations and supports the fueling demands of larger turbo setups.

Key Features:

• 100% Increased Fuel Flow: Bigger bore size provides double the flow compared to stock, supporting higher ethanol blends and larger turbos.
• E85 Compatibility: Fully compatible with ethanol blends for enhanced performance.
• Plug-and-Play Installation: No modifications, cutting, or splicing necessary.

Why You Need It: The stock HPFP on the BMW N55 engine has a limited capacity, especially when tuning for higher output. The FX-200 upgrade offers double the flow, allowing for increased fueling limits to accommodate larger turbos and higher ethanol blends. This makes it an essential upgrade for those pushing the limits of their N55 motor.

Tune Changes Required: Upgrading to the FX-200 requires calibration adjustments. It's crucial to apply these changes before starting the vehicle with the upgraded pump to avoid potential damage and voiding warranties. Spool Performance provides calibration details to your tuner or can help connect you with experienced tuners. Custom tuning is necessary to maximize the performance of the upgraded pump in your specific setup and driving conditions.

Low-Pressure Fuel Pump Upgrade: For optimal functionality and durability, proper low-pressure fueling is vital. Insufficient low-pressure fuel delivery can damage the high-pressure pump and injectors, which rely on fuel lubrication. Spool Performance strongly recommends planning your fuel system upgrade with appropriate low-pressure components to ensure the long-term health of your system and avoid potential damage.
