SPOOL FX-170 UPGRADED HIGH PRESSURE PUMP KIT [GEN1 S63]

Spool Performance FX-170 High-pressure fuel pump upgrade

What is the FX-170?

The FX-170 is an upgraded high-pressure fuel pump. The pump features a bigger bore size than stock which translates into roughly 50% more flow when compared to stock. The pump is completely E85 compatible and fully plug and play with no cutting or splicing of any kind required. The added flow will let you run much higher ethanol concentrations and also allow fueling for bigger turbos. The FX170 also is capable of running at 25% more operating pressure than stock pumps helping injectors flow more volume of fuel for the same opening time.

Why do you need it

The stock HPFP on the S63 Motors is severely limited in capacity when trying to tune and raise the output of the motor. The FX-170 adds 50% more flow to the equation and also lets the injectors flow more, raising the fueling limits on the platform and helping you run bigger turbos and/or higher ethanol concentration blends.

What does the kit include?

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 install hardware

Spool 10-micron filter unit

Our 10-micron filter unit boasts the best filtration available on the S63 market without any noticeable pressure drop in the low-side fuel system. The filter unit helps keep the high-pressure pump and injectors safe by protecting them against debris and is highly recommended.

Spool Ethanol Content Monitor

The spool ECA kit for the S63 features a digital readout of in-tank ethanol content and fuel temperature. It includes our SPOOL Ethanol content analyzer app on mobile and readouts are delivered via BLE 4.0 low-energy technology. BLE4.0 allows you to use your regular Bluetooth devices on your mobile devices while being connected to the SPOOL ECA module. Fuel lines used in the kit are braided steel nylon core fuel lines that are 100% E85 compatible.

Are tune changes required?

The upgraded pumps do require calibration changes. It is important to apply these changes prior to starting the car with pumps installed to avoid any possible damage and void of warranty.

Spool Performance can provide calibration details to your existing tuner and/or help you connect with established tuners who are experienced with these pumps. Custom tuning is required to get maximum output out of the upgraded pump setup for your specific vehicle setup and ambient conditions. Spool Performance is a hardware manufacturer and does not provide custom tunes, but can assist with questions your tuner may have.

Low-Pressure Fuel Pump Upgrade:

Proper low-pressure fueling is extremely important for the proper functioning and durability of the high-pressure pumps and injectors in a DI system. Inadequate low-pressure fueling can cause damage to the pump piston and bore as they are lubricated by controlled leakage of fuel. The resulting damage from low-pressure starvation is detectable and would be cause for voided warranties. Please make sure you plan out your fuel system build with proper low-pressure upgrades when necessary.

Are tune changes required?

The upgraded pumps do require calibration changes. Spool performance can provide calibration details to your existing tuner and/or help you connect with established tuners who are experienced with these pumps.
