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

The Spool Performance FX-170 Upgraded High-Pressure Fuel Pump Kit for the BMW N63 engine is a premium solution for those looking to maximize fueling capacity and performance. This upgraded high-pressure fuel pump (HPFP) offers a significant improvement over the stock pump by increasing fuel flow by 50%, delivering a higher volume of fuel and enabling support for high-power applications, including big turbos and ethanol-based tunes.

Designed with a larger bore than the stock HPFP, the FX-170 operates at 25% higher pressure, allowing the injectors to deliver more fuel at the same opening time. This is crucial for setups running full E85, hybrid turbos, or high-boost custom tuning. Additionally, the pump is fully E85 compatible, ensuring reliability in various fuel conditions. The kit is designed for plug-and-play installation, with no cutting or splicing required.

Included in the kit is a Bosch-Spec 10-Micron High-Flow Fuel Filter, providing the highest level of filtration for your N63 platform without compromising fuel pressure. This ensures long-term reliability by protecting your HPFPs and injectors from debris that could cause damage.

For optimal fuel monitoring, the Spool Ethanol Content Monitor Kit is also included. This device provides real-time ethanol content and fuel temperature readings via the Spool Performance mobile app, ensuring that you’re running the correct fuel mixture. The kit also features durable, E85-compatible braided steel nylon-core fuel lines that enhance the system’s reliability.

Why You Need It:

• Increased Fuel Flow: The FX-170 delivers 50% more fuel flow compared to the stock pump, allowing for higher ethanol blends and big turbo setups.

Ethanol Content Monitor Kit:

The Spool Ethanol Content Analyzer (ECA) Kit monitors the ethanol content in your fuel in real-time. It syncs with the Spool Performance mobile app via Bluetooth Low Energy (BLE 4.0) for seamless connectivity and includes 100% E85-compatible braided steel nylon-core fuel lines.

Tuning Requirements:

Custom tuning is essential when upgrading to the FX-170 HPFP. Calibration changes must be made before starting the vehicle, and Spool Performance provides support by offering tuning information to your tuner. Please note that Spool Performance is a hardware manufacturer and does not provide custom tuning services, but can assist with tuning inquiries.

Low-Pressure Fuel Pump (LPFP) Upgrade:

To ensure the longevity and reliability of your high-pressure fuel pump and injectors, a proper Low-Pressure Fuel Pump (LPFP) upgrade is essential. Insufficient LPFP supply can cause premature wear or failure of the HPFP due to poor fuel lubrication, which can damage components and void warranty coverage. It’s crucial to ensure that your LPFP is upgraded to match the high demands of your HPFP system.
